Interest on the show floor doesn't necessitate the massive sales that the Wii has seen, and that's because they've been marketing geniuses, but it wasn't set in stone the second the Wii was revealed and the same goes for MS and Sony.

Also, telling someone to "brush up on their history" for something that happened less than 5 years ago sounds really haughty.
