No, my 775 lineup was actually sarcasm. I don't believe in backward compability. Neither for AMD, nor in Intel. Even in spite of the fact that my lucky P5B-E motherboard already saw 3 different CPUs. But thats always lottery and many S754 and AM2 owners can say you that. Except that it is worth to replace motherboards sometimes not just for CPUs, but for new features.
If we put aside all new features comming in the next months (such as SATA3and USB3) which can alone justify mboard replacement, I really don't see motivation to use 6-core with DDR2 which can turn into bottleneck for many cores CPUs. After all AMD CPUs has less advanced mem prefetch/disambiguous technologes then Intel's Core.AMD has more choice and as noted the Phenom II's perform very well. Most likely AMD will intro a new socket in 2011 with intro of bulldozer but most likely so will Intel with sandy bridge. So what about LGA775 well its dead. AM2+ with split power planes/AM3 gives you more future prospects.
Also AMD uses the same socket for the high end, low end and low end and intel uses three "1366,1156 and 775". Intel has no plans to intro six core mid end processors in 1156 so that means no future prospects except getting either a i9+1366 or waiting for sandy bridge. If this is based on Istanbul "which it most likely is" they can use DDR2
Sorry it is not me who started speculations.
