The Athlon 64 X2 Energy Efficient processors are very good for HTPC's. They might not be as powerful as Core 2 Duos, but they're affordable, use less energy and doesn't require anything special for cooling which is perfect because you want to watch your media with a quiet HTPC, not a jet turbine.
As Ownage stated, AM2 was pointless. They could've definately gone 65nm on Socket 939. Besides, Socket 939 is still a viable platform, which pisses me off because they've virtually EOL'ed all Socket 939 processors when it is obviously still a capable standard.
I just hope they don't fuck up Barcelona. I ain't holding my breath for AMD, but I'll keep my fingers crossed for their financial well being.

The IMC doesn't completely eliminate the Northbridge, as other components still need it. It just means it has one less job to do.
