Looking forward to 6 core cpu's

If that was the case it could be out for half a year.
That it's launch coincides with AMD's next server platform with 6 and 12 core cpus might have something to do with the dice they plan to use.

That was the case. The Istanbul die is a pretty big die (346mm2) so the manufacturing cost is pretty high. While the AMD can sell this die for $450-$1000 then they won't offer it for $300-$400. It's a simple economic reason.



The other reason is that the AMD want to launch a complete new platform (Leo) and not only a CPU.

Six-core CPU + 890 series chipset + 5800 series VGA

Unfortunately for some (unknow) reason the 800 series chipset family is slipped into 2010. I think that there was some problem with the new SB.

As those G34 and C32 cpus won't even fit into current sockets DDR2 memory controller is a waste, therefore it's desktop variant would need AM3 socket.

The DDR3+DDR3 compatibily doesn't really increase the IMC size because the two standard is very similar. So they won't design a new die to remove the DDR2 compatibility because it would be more expensive than to leave that area untouched.
