from the small developers we have seen probably a hundred+ timed exclusives out/announced already.
..but it has less to do with profit and more to do with resources. even a moderately big team like super big games or jonathan blows team can't really manage platform parity across all platforms just because they don't have the man power. transistor will eventually come to xbone. the witness will eventually come to xbone. most of the other best indies like octodad, don't starve, outlast, mercenary kings, towerfall, axiom verge will eventually come to xbone but these developers can't seem to support both at once and sony leads the market both in sales and in respect for indie developers.
multiplat will always be more profitable.
the small teams that don't go multiplat are the ones that failed and can't afford the additional development to make a port. ...or MS gives the finger to by enforcing the parity clause.
