When the rumours started to fly, I called AMD and talked to Pat Moorehead who answered all of my questions. The B3s are not bugged, period. The fix was tested on B2 silicon and verified (Don't ask, the elves who work at the Fraternal Order of Silicon Repair Mythical Creatures Local 17 get antsy if you reveal their secrets).
Basically there is no B4, there won't be a B4, and the next stepping is Cx. The Cx parts are the 45nm Shanghai cores, so the B3 will be the end of the line for 65nm. B3s are going to be sampling in the not so distant future, production in the end of Q1, and retail availability in Q2. That part is a slip.
In summary, B3 is fine. It is a little later than people expect, but what can you do? The fixed chips are on the way, sit tight, it is only a few weeks before this soap opera ends.
AMD Phenom B3 has no TLB errata
