FUD Zilla has some details on the three Nehalem sockets that Intel is working on, the LGA1366 will launch in Q4 2008 and two LGA1160 sockets will arrive next year.
The first one is something we first time mentioned in late 2007 and it is the LGA 1366 or the first socket that will support Bloomfield CPUs. This is the first desktop CPU scheduled for launch in Q4 2008.
The other two sockets actually look quite alike, but they might be different after all. The LGA 1160 will accommodate Lynnfield and Clarksfield CPUs while there is an alternative LGA 1160 socket that can support Nehalem with an integrated GPU that will accommodate Havendale / Auburndale CPUs.
