This could possibly be partially true but if you look at the bandwidth of previous cards years gone by (and current consoles), theres many different ways to throughput/push that information. The 8800 GTS has a 256bit bus, and outputs 62GB/s. Thats alot. The 5900 series also had a 256bus (check below link) yet only was able to push 22-27GB/s max, or less.

The 360 has 512MB's of video ram available, yet only has a 128bit bus.

If the 360 can push what it does through a 128bit bus with 512MB of video ram, then it's quite possible the G9x architecture can push what it needs too.

2. The 8800GT is a 9 series card in everything but the retail name, its a G92 based card, and the 9600GT is a G94. They use the exact same architecture except that where the 8800GT has 112SP the 9600GT has 64 SPs, other than that the only other "improvement" is that nVidia is adding an optional DisplayPort connector.

For having close to double the shader processors, the 9600GT benches decently against the 8800GT. To me, there seems to be quite a difference between the cards given shader count and benchmark results. Another look at that NVIDIA stat link I provided shows that the 8800GT and 9600GT have the same exact bandwidth. 57.60GB/s
Seems to me the G92 and G94 architecture are quite different.

3. The 9600GT has been benchmarked several times, and it has been shown to perform about as well as an HD3870 in most situations.

The card isn't even out yet. Let alone updated drivers etc... The current benchmarks, while give you an idea, aren't complete nor completely accurate.

We aren't going to get a true next gen card until the G100 based 9800GTX which will sport twice the SPs as it's predecessor and have DX10.1/SM4.1 support.

I was only suggesting the possibility of things that may come with the 9x series. For all I know it could be dud. Or maybe not. Only time will tell...

Just read this here on Overclock.net, and followed the source link:

GeForce 9800 GX2 are now revealed. We already know that the card will have two PCBs, 1GB of GDDR3 memory, a 256-bit memory interface and two G92 chips but the fun part comes only now.

The 600 MHz-set GPU is (said) to have 128 Stream Processors clocked at 1500 MHz while the memory is clocked at 2000 MHz. These should help the GeForce 9800 GX2 beat the Radeon HD 3870 X2 but will also bring higher power requirements and a hefty price tag. The ETA for the GeForce 9800 GX2 is March 11.

More and more cards, including this one are being released with 1GB of ram. They also have a 256bit bus. It seems like this is a stock nvidia card as well. I doubt they would put a gig of ram on the card if it wouldn't be utilized.

EDIT: I'm no engineer, but I do realize the importance of memory bandwidth. I've made a couple posts a few days ago pointing out the importance of memory bandwidth. It's one of thee most important things about a video card. I just don't believe it's fully limited by the size of the bus. Possibly 3-4 years ago that may have been the case.
And especially with AGP. But even then, they found ways around it. Everyone said they wouldn't make a 6800 with AGP. Then they did. Said it would be the 'last agp card' in the reviews. Then they came out with some 7xxx series with AGP, and ATI just announced an AGP version of a couple of their cards...
