Intel shows running 32nm chips.

[Blauhung]

Hopefully Gulftown will be compatible with current LGA 1366 boards and Intel doesn't pull the usual "same socket, not compatible" game.

yup, drop in compatible

nope, notebook ram is longer, I suspect it's for flash memory to cut boot times (the tech has been announced long ago, but never made it to retail).

what he said, next version of intel's turbo boost memory.

is there a 32nm shrink of penryn core2 arch, or any other 32nm dual core... or is everything from here on nehalem / IGP based?

Nope, the uArch that makes up the Nehalem core is replacing it.

Core i5 will eventually be replaced with Sandy Bridge, although I presume they will get a different brand name than Core i5. Performance Sandy Bridge as Core i6 anyone?

Sandy Bridge (formerly Gesher) is the new uArch that will be replacing Nehalem. So it's really the upgrade for the whole line.

LGA 1366 and LGA 1156 will continue. 45nm 4C/8T i5 owners will go down to 2C/4T 32nm. But LGA1366 owners will get cheaper chips with 32nm.

So still 2 sockets.

Yup, and don't count out seeing a 32nm refresh of Lynnfield on LGA1156. This was probably going to be coming out 2010 after Westmere comes out Q4 2009 (same timeline as Lynnfield/Nehalem). Might be 4 core or 6 core (probably 4).
