Hopefully the Wii successor will get good 3rd party support from the start, like the 3DS seems to be getting. I'm not quite convinced it will, though. It really doesn't make a lot of sense that Wii didn't get higher budget titles, unless you factor in that
- developers believed Wii hardware sales would be a non-factor, so they allocated most of their resources to the HD development
- developers largely don't like Nintendo as a whole or the Wii in specific (which seems believable to me given the hate the Wii got from a lot of 'hardcore' gamers and the fact that a lot of game designers belong to that group)
- motion control input processing is something very new, and new things often need time to understand them. Also, there's a lot more data to be interpreted than button and analog stick input, and it's harder to interprete - swinging the Wiimote allows a lot more variance between swings even if you try to exactly replicate the motion, than moving an analog stick ever will. So it will be a lot harder to get motion controls done right than traditional controls. So the fact that motion controls are capable of lowering the barrier for casuals to get more into gaming is offset by those difficulties for developers.
I think the last point is underestimated by a lot of people. Nintendo is known for investing a lot of time and effort into the controls, and they have a head start because they start experimenting with the controls at the same time they are developing the controller. In my opinion a lot of 3rd party games (not only on Wii) show that the developer invested a lot less into the controls than Nintendo, and thus they don't feel that good. Casual gamers are less forgiving to controls that don't feel right from the start.
I'm quite interested how developers will treat motion controls in the future now that 360 and PS3 follow the Wii.
