I heard about this a little bit back... A digi-distributed WarioWare? If it's going to be a traditional WarioWare game I'm not sure why that's necessary, but I figure it's because the game is probably is about making your own games and little else--and, if it was store-bought, people could play it on a normal DS and weird things up. So I guess that means games that take advantage of the DSi's new features'll be sold as DSiWare? ...Well, works for me!
I figure there'd be more than two, though, especially considering Dr. Mario is about neck-and-neck now with Mario Bros. as the Most-Unnecessarily-Remade (but by no means bad) Mario game.
