The original Metroid recently came out in Europe, so that seems likely. I doubt we'll get Super before the first one.
My fingers are crossed for Super Mario Bros. 3, tied for best game ever in my book (with OoT, which already came out and I should probably go back and finish, I think I'm at the Fire Temple). It'll be the last Mario on the VC, assuming they never add Game Boy games, which I hope they do.
Another N64 game would be nice, too, and since WaveRace is coming to Japan tomorrow I guess that'd be the one. I've never played it, but I've heard it's good, so that's good. How about something besides a racer next time, though, Nintendo? Wave Race will make it 3 out of 7 racing games of the N64 VC.
