Unfortunately, it seems that a lot of AMD users out there hoping just to drop a new Bulldozer chip into their existing AM3 board (myself included) are going to be disappointed. The chip will require a new AM3+ socket, which is compatible with existing AM3 chips, but will not work in the current socket.
On the other hand, if they were going to do this, then I reckon they should have gone all the way and made it AM4 with enhanced features.

Maybe AM4 is on the way. How long did AMD take to release AM3 when they just launched AM2+?
