I agree. I'm also a very big believer in umbrellas: that is, a select few games draw in an audience to a particular platform, and the rest of the titles bathe in the wealth as fans of game [X] look for more [X]-like games to play (this doesn't even necessarily even need to be the same genre. I think Dissida benefitted from the MH crowd, for example). Wii Sports and Wii Fit are games that fit that description. So is Monster Hunter. So is DQ, but until I see something on the plate that looks like it's launching within, say, a year, I don't have much to comment on.
I think my argument would be that too many umbrellas have already been opened on the PS3 (specifically, Metal Gear, Dynasty Warriors, Yakuza, Resident Evil) and FF XIII has been anticipated for so long it might as well have been. In comparison, MH to Wii was a surprise and will really be the first Umbrella title to launch on the Wii.
We'll see. Again, I think it's too late, but I certainly could be wrong.
