Always look at the bright side of life.
Actually you brought out one point, which actually turns this weakness as a strength. Since it's easy to market games with graphics, this is where the developement focuses, which eventually leads to disappointments, when the actual gameplay is secondary and people stop buying games since their movies look better anyway and they don't need to suffer shitty gameplay (equaling industry crash).
Basically Wii forces the developers to focus on the game itself, instead of focusing to finishing the graphics, when finalized gameplay gets gamers more happier.
The reason why some of developers don't like the Wii, is because in order to success, you need to be creative (or have model that "fits" the Wii). Upgraded graphics don't require much creativity and lets devs easy (although expensive) route.
In the next gen, i belive that the creative studios are going to be the "strong" ones in the industry (not that the wouldn't be already).
@Zucas: I don't think Nintendo plans to release new console early, since you are now forgotting the Nintendos strength, which lead Wii (and DS) into success. The headstart didn't lead Megadrive to beat SNES, or 360 to beat Wii, it was Nintendos ability to innovate and be different from the competition. Let's say that N6 would come out year early to PS4 and 720 and you would control the N6 with your brains electric activity, the year would mean that competition would have enough time to copy the controller and the software. So, i can assure you that Nintendo will start the 8th gen last.

Nintendo games sell only on Nintendo system.
