The signs to me are nothing more than theming. "Sidewindin'" is a general "western" term for fancy maneuvering, which indicates the layout of this coaster.
You all seem to forget the fact that if CP tries to hint things at you, they do it directly. Signs were posted everywhere during MF's construction telling you it would be a record breaker, for example. This ride's signs are far too dodgy to be considered as anything but theming.
I don't see the wingwalker concept at all here. The Wingwalker is proposedly HYDRAULICALLY launched, not LIM - it is simply a train refit for Accelerators, a ride type which CP surely aren't getting (management has stated their unhappiness with said system because of Dragster's issues).
I also don't see anything new or prototypical. What was the last prototype CP built? I don't recall one. CP really only builds bigger versions of rides that have been done already - not new ride types/styles themselves.
As for records? I don't think it will break any. The height/speed records are pretty far fetched in my opinion, given the footer layout, and the inversion record is absolutely ridiculous. In a recent issue of Rollercoaster! magazine, I read how "Kinzel considers inversions to be gimmicky in nature" (ever wonder why CP has so few loopers?) - why would he make himself a hypocrite by breaking an inversion record?
Intamin Inverts are out of the question. The footer layout isn't right for it, and CP already has the Inverted side of things covered, with a Suspended coaster, an inverted launcher, and an inverted megalooper. What's left?
Honestly, I have to say that I favor the AquaTrax concept here. The seats are saddle-style, the ride is an LIM launch, and the layout looks very similar to the only existing AquaTrax - Atlantis Adventure.

The footers are also similar.
This concept also allows CP to build something that has been tried, tested, and proven - but on a bigger scale.
The final thing - the ride's proposed name, Maverick, represents a wild animal. What else to fit that name than, say, a wild bull-themed AquaTrax car with "saddles" on it's back to sit on? Hmm.....
