Depends what you mean by "pro style." The majority of these terms are so completely meaningless at this point when you can categorize both 2015- Alabama and something like Missouri under Pinkel as spread. Pro style college teams largely have to live out of under center to be categorized as such, but teams like the Chiefs, Packers, Saints, and Patriots are largely running spreads, not to mention teams that are working in the read like the Seahawks or Panthers. RPOs don't disqualify a team from being "pro style" since Favre and the Packers were running them in the late 90s/early 00s.
I think the WCO is still around, though it's certainly a smaller number of teams. Some big names like Michigan and (I hesistate to put them in the same category but they get a fair amount of coverage with Rosen) UCLA are running it. The WCO in its pure form is probably going to become a novelty, yeah, but it's never going to die out. Leach's air raid is basically the WCO on steroids. Though the air raid again brings up the meaningless of labels, since you have "air raid" teams running 50-60% of the time. Yeah, they run the concepts, but it's not like the raid invented this stuff. They're largely West Coast concepts.
The future of football is almost certainly these "multiple" offenses that match West Coast stuff with spread stuff, at least in the NFL if they want to remain a league. College is always going to have that variety, because Kansas can't line up and run the same thing OU is running and win very often. It may change if/when they decide to go to four super conferences, but even then I think there'll still be more variety than the NFL.
