Hmm yeah I have no idea, I mostly read this which really intrigued me but I don't really understand all of the technology and science behind it http://www.intel.com/pressroom/archive/releases/2010/2010072...

I had always gotten the impression that even if it they couldn't get as small the impact of less heat and the ability to cross beams could allow them to be denser. But like I said I don't really know what I'm talking about :)

You can't cross light beams at 7nm, if you had a "crossroads" structure" it would simply diffract round the corner and exit at all three other points.
