i realize this might increase latency or something, but is there any possibility of this happening?

No. Especially no to the sphere idea. Circular dies would be a waste of wafer real estate.

What would be the point of shrinking transistors if you're not going to pack them closer together? Lower operating voltages from shrinked transistors would be negated by higher resistance from longer interconnects. Skew would be ugly as well.

You pack them together so you can have more of them. If you need even more, you get a bigger die. Bigger dies are expensive, don't yield as well, are tough to make... it's generally a good idea to stick with a smaller design unless there's a demand for something big.

The more technology grows the faster it can improve and perfect itself. I predict perfection of the silicon to be here by 2020. Just a estimate.
Yay... Nano tech

Notice how they did not mention silicone wink.gif The news was about starting research into 7 nm and 5 nm processes.

Anyway - this stuff would not need 10+ years of research if anyone could step in and tell "this will not work, this will work and this is how you do it". I'm pretty sure Intel researchers are very aware of properties of silicone by now. It remains to be seen if they find a way to shrink to 7 or 5 nm. I personally have some reservations about that based on thermodynamics but who knows - there might be a way perhaps. More precisely my reservations are not about if this can be done but more about durability and reliability of such structures. Entropy is a harsh mistress if you get down to that scale with very large concentration gradients in combination of high temperature and some potential differences on top of that. Without coming up with some pretty incredible engineering feats the chip would last perhaps few days at most when done at these scales based on today's knowledge.

Make them faster? Everyone seems to forget we have a whole other path to go down still. Even if they hit a wall for shrinking somewhere between 10-5nm, they can come up with something that would allow much faster switching of transistors, as in faster clocks/more IPS. Everyone is quick to dismiss faster clocks probably due to the whole P4 debacle. Given an impending dead end for shrinking, you can bet they are looking into ways to improve IPS, whether it be faster clocks or IPC. Just throwing out graphene because it is widely known already. Apparently it can increase the transistors switching speeds by an order of magnitude compared to current method's. Not saying it will be used, just given an example of a whole other path to think about.

If we can't shrink the transistor to allow more in the same space and power envelope or find any other method of adding more transistors(stacking, etc), then the logical choice would be to increase the rate at which they can switch on and off and/or increase how many instructions can be executed with each on/off cycle. I'm sure given enough money and time spent, they can find a way to increase clock speeds, IPC or whatever it takes to increase IPS overall. They don't do it now, because it is easier and much cheaper to just do the same tried and true shrink, pack more in strategy. I could be completely wrong, they may come up with something new that we would never think of. I'm just thinking of, what seems to me, the most logical way to go once we reach the shrink limit....speed those things up!
