However I suspect this isn't in their interests currently :(
I suspect the issue is more that they'd have to tape out a new die to make the necessary amendments to a native quad core, and that bulldozer / bobcat / whatever are close enough to production yields that it's not worth pushing out a tweaked Deneb core in between.
One thing we can probably assume, however, since the 9x0T variants never made it to market, is that they're yielding well enough to sell all of the Thuban dies as hexacore processors. Bottom line seems to be that they're going to line up slower hexcores against the existing quad cores and ask people to choose either cores or clockspeed. For my money the hexes are the ones to go for: particularly if they undervolt well (could get a 70Wish hex for your money at 1.05V) or overclock well (you could probably get a 3.4GHz hex for less money than a 965BE….).
