It supposed to be a cradle attatchment to the Rev. so you can play regular like a gamecube...with a few extra buttons. But this picture isn't official. You should wait till Nintendo officialy comes out with pictures...not some other website.
Sweet it looks awsome I'm definatley getting Rev. now will it work for actuall Rev. games just curious
Well, that depends if the Gamecube game itself is backwards compatible with the Rev. If not, then no. But most of the time almost all the games work with new systems, so I am pretty sure that most Gamecube games will work with Rev. If not, then you probably have to download them to your Rev. .
GCN games are compatible, and Nintendo has confirmed the existance of such a shell. That PARTICULAR one, however, is a mock-up by IGN. We don't know what the actual shell will look like, but it won't be that.
