I have low expectations for voice recognition. It will definitely revolutionize interacting with NPCs in the future. It seems clear to me that motion gaming will be made more intuitive, however less complex. Still interesting for casual gamers. On the other hand it will also add some features for core gamers. I pretty clueless what it will add. Grabbing ammo/objects/grenades , kamehamehas 8) or giving directions in tactical shooters. It will add gameplay elements, it probably won't reinvent a totally new control-scheme for core gamers. It will probably mix quit nicely with 3d gaming.
