Indeed, rumors on the webz are that the 1156 socket will see no more than quads. The 1366 will definitely be getting the gulftown i7-980x which is a hexacore. However, recommending platforms based off of rumors and heresay is not what we usually try to do here. Also, unless you plan on doing video encoding or some other highly threaded application, the same goes for a hexacore, 8 core, or 100 core, the games right now very rarely even use quad cores. As far as upgrade path, yes, the 1366 is the way to go. But you will not see gains in that platform for a long time, and by then there will be something better:)
[Edit] btw, I have a 920, but only because I got a deal on it. I'd have a 750 if I were building today.
