I agree that holiday launches help - but just to pick up on the point re. DC and PSP, DC took over two weeks to sell what PSP sold in two days. Is 500k units in 2 days disappointing? It's all relative to the goals you set yourself, so from that point of view you could say it was disappointing for SCEA (who probably hoped to move 1m very quickly). But in absolute numbers, the PSP launch was a better one than DC's, and thus compared to it can't be considered disappointing.
