This is the sort of flame bait thread that should be deleted before it even receives any posts...
We haven't accepted Wii U as having lost because it hasn't yet and we don't want it to. Wii U certainly isn't doing well, but PS4 isn't doing as great as people on this site seem to think it does.
Are stores clogged with people asking for the PS4 every morning? The Wii was, same with the PS2 for as long as a year after the console was released. This tells me that the PS4 actually isn't that enticing of a console. Sure it's selling out, but that doesn't mean much.
In popularity poles among the casual players, XBox One usually wins out. I asked my mother, and she was convinced the XBox One was the console to have. Same with several other sources I've seen.
I don't see it doing the 100 mill that people seem to think it will, and I think it's left itself open to be overturned.
