Dont know if thats any kind of news.But from the article:

On the server front, Siefert said that the 16-core "Interlagos" Opteron 6200 processor, the first server chip to make use of the "Bulldozer" core and implemented in GlobalFoundries' 32 nanometer processes, would ship this quarter to OEM partners. He added that the chip would offer about a 35 per cent performance boost compared to the current 12-core Opteron 6100s.
Thats pretty much exactly increase in core count.12+35%=16.2.
