Err...just because one game was confirmed doesn't mean the entire list is true.
No one had even heard about Tank! Tank! Tank! until E3. It's either real, or it's bullshit made up by a Namco insider with only one true game
Edit: For the record, this list was supposed to be just eShop games. That explains why the launch list isn't on there, but isn't Tank! Tank! Tank! a retail game?
