They are coming out after the Core i3 and Core i5 is being released in early January. The Core i3 and Core i5 dual cores will have HT enabled and are built on a 32nm process and have a 45nm IGP integrated on the processor in the form of a MCM package.

After this the Core i9 will be released on a 32nm and no doubt the socket 1366 Core i7 and socket 1156 Core i5 and Core i7 processors will follow a few months later. The 32nm process will be used by intel for a while longer. TBH, I could wait another 6 months to 9 months until the newer Core i5 and Core i7 processors are released and BTW DDR3 RAM and the associated motherboards will have dropped in price too as socket 1156 becomes mainsteam for the Intel platform. TBH, I would rather not pay the premium in price and potential initial bugs for being an early adopter for any entirely new processor socket.
