@Nightsurge: Well now, unless it gets bundled and M$ driving it forward to devs, to get it implemented into all the games from now on, it has no widespread future.
I don't know if the controller has a controller for the second hand, but if it doesn't, it's going to limit severely its useability in most of the games, which means that it basically limits itself only into number of categories of games (meaning limited success).
M$ may not be interested in supporting the peripheral due to their next gen plans. Since their Xbox ventures aren't going to turn into profit this gen and Nintendo is going to end up as a winner this gen, they need to hit next gen to edge out the competition. M$ doesn't want to spoil their next gen potential by marketing it this gen.
Also, they're doing rather good at the moment, especially when Sony is doing relatively bad (who M$ wanted to shoot down).
