This is the same guy who couple of months back published the VB 12 hours before the DOS. His information looks correct.
"It is also worth noting that worldwide, there were almost 156,157 EB numbers available for FY 2010 and this year FY 2011 (October 1, 2010 to September 30, 2011), there will be only 140,000 EB numbers, due to the statutory scheme by which numbers are allocated and unused numbers are allowed to be freed up for worldwide use during the last quarter of the year."
for FY2010 no FB spillover

. total EB # 140,000.
no quarterly spillover. looks like no EB2-I movement till July2011.

For oct and nov, Eb2-I already used 700 visa and those were not in demand... means maximum of them are porting from eb3->eb2
