360 will maintain its lead over the PS3 in 2010.

I expect 2010 Q4 to be a lot closer than 2009 Q4. 360 may actually sell more consoles worldwide than PS3 in 2010 Q4. With recent adjustments in and the PS3 barely outselling the 360 in the opening weeks of 2010, the PS360 worldwide sales gap will not fall below 5 million in 2010.
Expect PS3 to sell around 12 million in 2010. Lower than 2009 sales total, PS3 cooling off in late stages of 2010.
360 will sell between 10 to 12 million, it all depends on Natal success. 2010 could be the 360s highest selling year on record eclipsing the 11 million sales in 2008.
