I'm less interested in what launches than what comes out in the sixth months after release. That seems to me to be the make-or-break period that establishes the momentum for the system. In that first six months, they should obviously have Mario, hopefully with more innovation, an FPS and RPG . The FPS could be a second Geist as long as it turns out well. At some point, a Western RPG like Fable or Morrowind would really help ground the system. Hopefully, however, Oblivion will come out for the Rev and solve that problem. SSB is an obvious must; with better marketing, I really think it could beat out Halo as a college game. Another Resident Evil in that window, together with the FPS, will help establish a more mature theme. Both games should invest heavily in stunning visuals - as we saw with RE4, that's what gets the hype really rolling for mature games and helps change the image.
And, of course, there should be entirely new games. And at least one of these should be mature. Part of the reason Nintendo's innovations get treated as gimmicks is because their really innovative games tend to be Pikmin, Pacman, and Animal Crossing. I guarantee you if the Pikmin had been armies of shambling zombies, it would have made a much bigger splash. Do all novel game concepts have to involve bright colors and happy noises? The only reason I can see for Nintendo to restrict itself this way is simply the belief that they'll get more money with that E on the cover, and at best that's shortsighted. Be a little daring, Nintendo. Reach a bit for that 14-28 demographic. They're the big market, and they have a limited appetite for cutesy.
I would like the Rev Zelda to be huge. Not simply in terms of geography, with tons of filler like they had in WW, but a long main quest with at least ten full dungeons, minidungeons, extra powerups, side quests, colorful npcs. For extra powerups, they should bring back spells and have many more special attacks you can acquire, although you would only be able to get a few of them with any one character (thus adding a little more RPG and replay value, and making combat more diverse). With all that in mind, I don't need to push for Zelda coming out in that six-month window. Besides, Nintendo can't front-load the launch schedule too heavily. You can't just rely on 3rd-parties for the next two quarters.
But if you want to get third-party support, you have to sell systems, and if you want to sell systems, you have to have lots of games pretty much from the getgo.
