I'm not too fussed about what might or might not happen. But the concept of a Supercharged bike makes a lot of sense to me. The possible outcomes are endless
Smaller Engine, Same Power, Less weight = Same Performance
Same Engine, More Power, Same Weight = Acceleration (everyone seems to want)
Same Engine, Same Power, Same Weight = Better MPG
and on, and on, and on...
Seems logical to me, cars have been using them for years. Obviously the same goes for Turbos, but I really think Superchargers make more sense in power delivery for a bike than does a Turbo.
