I think that the reasons given - that the PS3 attracts a bigger fighter base, may be correct.
However, like many games before this one, 1 week of data will not tell the story. There have been quite a few games to do better on one system the first week, only to see much better legs later on. I think that, given the bigger 360 install base, we'll see SFIV have better drops on the 360. Call it a hunch ;)
Back from the dead, I'm afraid.
