Poko desu! Reporting in!
My Wal-mart has three copies of Bayonetta 2.
Also, four copies of Hyrule Warriors, and six plus of the big Mario games. Er, and one copy of Madden.
However, I HAVE confirmed at least one Wii U owner in my area, as the Wii U had no less than THREE games in the used rack (Mario Kart was $52).
While I was counting, a guy came up with a kid and said, "you can't have any Wii 2 games 'cause we've only got a Wii." He seemed to be struggling to tell them apart so I pointed out that they were in the white boxes. He told the kid that he could have any one of the $19 games and the kid yelled out--I'm not making this up--"I WANT BATMAN". Yes, a core third-party game chalked up another sale on the Wii.
I couldn't find Funk Barn.
The 3DS was the only system with TWO racks, everything else had one.
That was my report. You don't know how long I've been wanting to get in on this.
