Actually, I think that what I'm the most excited about, is the desire of a future once defined, a long time ago, like the reflection of numeric convergence: Simple, easy, efficient. With the Wii online possibilities, which allow DS demos downloading using Wii, I just think its excellent. Not to think that it may be used also for Wii demos. Which remind me that Nintendo used to never want people to have a look about their upcoming games.
The Virtual Console is also interesting, because be able to play old games easily, for a fair price, and I hope, based on the same as the one used to sell ringtones, look great. Pay 1€ or 2 for a NES game, few € for a SNES game, less than 10 for a N64. Well, I'll be pleased only if the price look that way.
By the way, Nintendo recently state that there could be an occasion to offer named "indie" (read "poor, but innovative") developpers content, which again, seems great to me. After all, be able for few € to buy concept-games (like Gish), using Virtual Console, seems reasonnable and tempting, even if the idea is from Microsoft (well, the console-based concept utilisation at least).

And well, do I have to say again why the Wii's games gameplay might be, at least, just terrific ?

So, I'm dying waiting to play it, and to say that Nintendo was able to look so much better than the way they look before, considering they were slowly dying. Keep up the good work.
