I'm not sure if Nintendo's gamble with the Wii's control system will pay off. The DS is certainly doing well, but that might have more to do with Nintendo's existing dominance of the handheld market, and the PSP's less than stellar performance so far. The home console market is a whole different matter, and one in which Nintendo is already lagging behind. They'll always have a solid fanbase in Japan, and the hard core of screaming fanboys in the west, but what of the middle-of-the-road, undecided gamer? Given a choice between the three next-gen consoles, the Wii's control system may well be off-putting. The simplicity of the Wii pad more or less rules out multi-platform conversions, so say goodbye to all of your favourite sports titles and FPS games. And if developer support for the new system is poor, then we'll see very few third-party projects for the system at all. Of course, there'll still be the Nintendo classics: Mario, Zelda, Metroid and the like, but will they necessarily be enough, particularly if we just get Mario Sunshine with a funny control system?

Of course, if Nintendo manages to capture the casual, non-gaming market then this won't be a problem. But the general public are a difficult bunch to please, and may well fail to be impressed by the Wii's new approach to gameplay. After all, is it really fundamentally all that different to the Eye Toy, in that it offers a simpler, more physical way to play games? Distinctive control methods are nothing new, and they haven't set the world alight in the past.
