I ran the numbers, and I agree it is possible. Given the higher price of the PS3, Christmas is it's only shot of having enough sales for it to do better. Failing to have much of a boost Q4 means it will almost certainly continue to loose market share in Americas.
I predict Q1 will be decent % wise, but that is more due to supply constrain of the wii, then the PS3 actually doing good. However, unless something changes, Q2-Q4 will have market share bleed by the PS3 in 2009.
2010 is more probable with no improvement, but 2009 is possible. It's also possible for a price cut, some unannounced exclusive to be release for the PS3, and for supply to meet demand as saturation nears and sales of the wii to fall closer to that of the 360. Another thing that would help PS3 sales is if they ever managed to make BC available on the low priced model, perhaps even dropping the PS2.
