I just heard back in a very short email from a friend of mine who works at one of the top 15 component retailers in the States. Naturally, I can't give his name or company since giving this info would be grounds for dismissal.
Remember, this is only anecdotal evidence but I've been hearing the same from quite a few of my contacts:
Sales so far:
FX-8150: 89
FX-8120: 97 (higher due to one client buying 20 units)
FX-6100: 22
FX-4100: 18
And for reference purposes, according to him in that same period of time the 2600K has sold 265 units, the 2500K @ 312 units and since its release the 3930K has moved some 74 units.
To make matters even worse, according to him there hasn't seem to be much (if any) new stock of the two FX-8000 series processors coming through the supply channel for the last three weeks or so. We haven't seen its effect due to the fact that the processors are selling so slowly. One distributor even sent out a discontinuation notice for the FX-8150 last Wednesday since they have no ETA on resupply. So while it isn't discontinued, any retailer picking up on this particular distributor's feeds will list it as such.
On the flip side of the coin, this retailer will also be selling Interlagos-based CPUs and demand for the Opteron 6276 in particular is through the roof.
So this should tell us two things: Bulldozer's mass market SKUs are selling albeit quite slowly (supposedly ~75% of the unit sales happened in the first two weeks of availability) but the server / HPC SKUs could set some sales records.
