^^ There is no news from the amd side,but its upto the manufacturers what and how they want to implement...gigabyte,asrock,msi and somewhat asus have changed their proccy socket from am3 to am3+ on their current lineup of 8-series motherboards.
Guyz with the old chipsets(7xx series) u all are missing the fact that the bulldozer processors have 1 pin more that makes these processor incompatible with am3 sockets...
unless the manufacturers comeup with a release of mobos (7xx series) with am3+ socket.
The only difference between 9xx series mobos and current 8xx series mobos
1.hyper link transport 3.1 present in 9xx series mobos.(not much of the difference as against hyper transport 3.0)
2.uefi bios.
3.better communication between north bridge and following chipset.
4.As for the memory controller its in the processors now-a-days..
IMO its better to invest in established technology then to believe in upcoming such as the p67/h67 sata problem.
what a user of amd platform can do is get these 8 series boards,invest in a good hex/quad core processors, as bulldozers establish themselves he can change it to 6~8 core bulldozer later. quite a good upgrade path.
PS. launch date for 8 series motherboards with am3+ socket is in april by most of the manufacturers.Good for people buying amd systems at that point of time.
