> By 2009, game developers will face... CPU’s with: 20+ cores

It seems like he was off by a matter of a few months at most.

I have a quad AMD Opteron(tm) Processor 6172 (Mar 2010) 2U server with 48 hardware cores. This motherboard can also take the 16 core CPU's which were also introduced the following year, which would put it at 64 cores and 128 threads.

The Opteron 6 core CPU's were introduced in June 2009, so a quad server would be 24 cores, or 48 threads.

Of course, that's not cores in a single CPU, if that's what even what the prediction was referring to, but that probably wouldn't matter very much from a gaming dev perspective anyway. It was probably a pretty good guess, all things considered.
