Raquet Sports actually looks pretty decent. If I didn't already have Grand Slam, I might consider getting it.
I don't think camera alone is "the future." Even a sophisticated array of sensors like Natal can't replace a thumbstick for moving an avatar through a 2D plane. These camera controllers are limited unless they're either supplemented with a controller (as in Arc/Gem/WhateverthefuckSonyisn'tcallingtheirdevicetoday) or unless we add more sensors we haven't thought of yet.
There are a few game types that could play really well with camera controls, but I don't think that the gameplay excellence is diverse enough to support a whole game console with camera alone.
