They will actually make a 16:9 version of all characters, stages, etc. So basically, you'll have the 4:3 version and the 16:9 version of the game, literally. And some people said that the 16:9 game actually made some stuff weird in-game, like Petra's projecttiles. However, all of that should be fixed until the actual Console version, or so I would like to believe. Since we are talking about Arcsys, it probably will.
