It's not a matter of should they, it's a matter of could they. I don't think Nintendo would let Sony handle their poster boy Mario because I mean have you ever seen Mario on a console other than one made by Nintendo (other than the Philips CDi, may we all forget it's existence).

Thats exactly what i was thinking! sony would totally be like " mario? uhhh.... guns, yeah lets add guns to this shit because we're sony and we think guns make everything better" haha funny i almost said somthing about guns in my post above.Yeah super mario rabbids looked way different then any mario I've ever known. That said, sony would more than likely turn it into some type of gun mini-game or something. I don't ever see this happening.
