I don't think there's going to be a whole lot of motion-only games to be honest.
Said games would not be playable in a lot of settings the Switch is supposed to function in like an airplane, car, bus, train (important for the Japanese and Euro markets especailly).
Of the 25 games shown by Nintendo and developers so far only 2 are motion only (8% and this number will likely drop as we see more games).
