And there's the problem. Very few publishers are striving to achieve a middle ground, instead opting to keep all of their best games on the HD consoles.
I'm not saying that the 360/PS3 shouldn't get these games - quite the opposite in fact. A lot of these types of games should be on the HD consoles because the power of the 360/PS3 is so integral to them.
That said, there's many games that could potentially be a superior experience on Wii purely because of the controls (especially with MotionPlus). I'm not talking about games that have come out (or will come out) on the HD consoles, but rather types of games that are radically different and make the remote integral to the experience. Some 3rd party games have done this already - look at Boom Blox as an example - but none of these games have been of the same scope or quality as the best 360/PS3 efforts.
The problem is that few developers are willing to push this envelope. Instead they're sticking to the safer route of putting their best games on 360/PS3, something that I have to question considering how many studios are being shut-down and how many are losing their jobs.
They give the scraps to Wii when they really could be taking advantage of the controller and delivering some truly impressive content. I'm not saying that all the best games should go to Wii - far from it, in fact - but on the flipside they're barely giving the Wii anything, when there's a goldmine that's just sitting there waiting for someone to make a real effort.
