LBP2 will be fine. But rather than being more front loaded in sales than LBP it'll have a similar but slightly higher sales pattern as LBP. I wouldn't expect much in the way of increased PS3 sales from LBP release in 2010, but in January PS3 sales might get a wee HW boost.
What will really miss out in sales during the holidays because of this is Move. LBP2 was one of those titles with optional Move functionality that could have drawn a reasonable number of people into getting Move. So I think whatever predictions you may have made about Move sales this holiday adjust them down by about 5-10%.
