According this very tiny news post at Fudzilla, its possible that AMD is still going to be coming in Q2, even though we had previous heard the B3 stepping was pushed back into Q3. 
Phenom 9600 at 2.6GHz will launch with B3 revision at some point in late Q2. You should be able to see and buy this CPU before July but we don’t have any better date that that.

Previously we heard that 2.6GHz will have to wait for 45nm but this won’t be the case. The faster chips will probably have to wait for 45nm that is still scheduled for second hanf of 2008.

At this time there aren’t any more precise dates and we simply hope that AMD will be able to meet its original plans as it has to start raising some cash as soon as possible.
