Second, 1155 has 16 PCI-E lanes. X58 Has 32.
Now, I don't really see why people are so darn confused over two platforms. Did you already forget about 1156/1366? In many cases the regular mainstream 1156 performed just as well as the enthusiast 1366, until you wanted MORE than what the mainstream offered. The 3820 chip fills the same role as the i7 920, a cheaper chip to allow people into the platform that may not need the the ultra-high end EE CPU's and later the hex-core. People that wanted more slots, more spacing, more SATA ports, more overclocking ability, more something that qualified them for the enthusiast boards.
Also, why must everyone insist on comparing SB-E to IB? Yes, we know IB has better IPC (slightly) and is faster (by a tiny margin). We also know that the IB-E chips will bring the same enhancements for the X79 platform, so all the more reason not to buy a $600 CPU and grab a hex-core IB-E when it comes out. In the mean time, we can enjoy our build with the 3820 which is pretty much a socket 2011 2600k for cheaper and slightly less OC ability.

Your analogy is a little off. Firstly, the 1366 socket came out first, so most of the early adapters of nehalem bought a i7920 and a 1366 board first. Afterwards the mainstream platform was released, and the general consensus there after was there was almost no reason to get a 1366 board over a 1156 board. The extra memory bandwidth doesn't provide any tangeable performance benefits in real world applications. The extra PCIE lanes provide no tangeable benefit it dual crossfire or sli solutions, in provide a minimimal at best benefit in a trifire or trisli solution.

The situation this time around is the same. Its possible the additional pcie lanes on lga 2011 might have a bigger impact on gaming performance then 1366 had over 1156, but its unlikely. I have seen any good reviews on the subject yet, so lets reserve judgement. The extra memory bandwidth is still a non issue. The price and incentive for 2011 is even worse off then 1366 however. Early adopters of sandy bridge bought the mainstream platform this time. There is a larger and better selection of mainstream board to begin with. The boards are cheaper and perform the same in nearly all circumstances. Also, a superior micro architecture in ivy bridge will be out at almost the exact same time as the CPU is released. IVy bridge IS faster, IS far more efficient in terms of power consumption, and will be much, much cheaper. People can still buy the CPU and a LGA 2011 board, whatever. But it isn't cost effective, and it doesn't make sense based on the information we have currently. If someone wants to justify the purchase, justify it correctly. The correct answer should be "its because I want it".

Same goes for the 115x platform and how Intel keeps chopping away pins for new processors(1156, 1155, and 1150). A significant portion of the pins aren't even being used yet. Based on historical trends and my aforementioned reasons, one has every reason to assume that 2011 will be around for the typical Tick, Tock, Tick or about ~3 years or about as long as Nehalem.

Has intel confirmed that it will be compatible with haswell? A quick google search hasn't found anything on the subject. If so, as a long term investment that would make sense. I am pretty skeptical about the notion though. The community wisdom is "by for today, not for tomorrow". I think that might still apply here.

EDIT: I just wanted to clarify this post, by saying all this criticism of 2011 is in the context of buying it with this quad core processor. For the person who wants the best of the best 2011 makes perfect sense. For anyone who is on a budget 1155 is in nearly every way more practical.

Right now my P67 board has to shut off its USB 3.0 ports in order to use an x1 slot for a sound card if I have my x16 slots running in x8/x8 mode. The only way to solve this would be to add an NF200 chip, which I have tried and don't particularly like. A SB based quad-core is just as fast as the SB hex-core CPU's for gaming, why would I spend an extra $300 for something that will do me no good? Obviously it makes sense for data-crunching builds, but not for me. I simply need more lanes for running multiple GPU's to power a 5760x1080 120hz setup (most reviews trying to show bandwidth doesn't matter are at normal gaming resolutions where it indeed does not matter much). Yes, I am in a minority. But there are people who need the same thing as I do. That extra I save by not buying the hex-core that will not be used fully can go to new waterblocks, etc. It has a purpose and a good price, which is cheaper than the equivalent IB 4-core 8-thread overclockable chip you insisted would be a better value. Will it be a bit slower? Sure. I'm willing to trade that for the features I can get on the motherboard.

So my question is what should i do with my upcoming build? I want to go with a quad core and either two 7970's or 680's. Will Z77 support 16x/16x without an nf200 chip? I dont really wanna run 8x/8x with those beasts. Then again, if i went with 2011 and a 3820 i wouldnt have to wait around until April...

In the end mainstream SB CPUs are still limited to 16 lanes so NF200 (note that NF200 doesn't add lanes) doesn't really make a difference other than introduce latency.

Even with the NF200 you're still limited to 16 lanes. Let's say you have 2 GPUs which are connected to the NF200 at full 32x, but since the CPU is limited to 16 lanes, it communicates with the NF200 with16 lanes.

NF200 allows more usable PCI-e lanes but that's about it.

I'm aware of this, that is part of the reason I am moving to X79. I think you misunderstood what I meant. With the switching chip I could use 3x GPU's and a sound card on an 1155 board, although it spreads the bandwidth thin and add latency I could at least fit it all.

Lol. Dang. I was waiting for Ivy but idk if I can hold out much longer. This is tempting, only for IB-E though.
