As I write this, Eric Bostrom on a carbureted ZX7R is leading about 30 fuel-injected bikes--GSXRs, 998s, R7s, and RC51s. He doesn't appear to be at any disadvantage.
You're right, FI is the future, but it has more to do with smog laws than performance. The fine tuning required to keep emissions low yet provide good throttle response can be attained more easily with the precise mapping of digitally controlled FI.
The advantage of carburetion is that it's familiar technology, well within the abilities of a shadetree mechanic to tune. The Power Commander is bringing fuel injection up to that level, too, but there's still a black-box quality to it that limits access to those with highly specialized knowledge.
