The problem with 3 slots, as I've said before, is that you likely won't be able to find all the old games you want. Sure, they could reproduce those games on the original carts, but what kind of sense is there in that? You would be wasting money making games on 3 different mediums, whereas having one disc or card would make things that much more simpler. I love the idea of entire series being put onto a cart. If it even had some extras, like those on DVDs, you could have some pretty kick-ass compilations. Just imagine all the games in a series fully reproduced on one cart. Zelda, FF, Mario, Kirby, DK, Star Fox, Sonic (Yeah, even SONIC!).
