I'm not a fan of the automotive-style five speed manual. Given the way people thrash on their SxS's, you'd be putting in a new clutch once a month. I look at all the mudders, all the rock crawlers, and all the dune bashers, and I'm just not interested in a clutch pedal.
On the other hand, if it was a dual-clutch style with paddle shifters (Honda), then that might be interesting, depending on the weight difference versus a CVT. I think Polaris has a patent on some sort of a selectable gear ratio system for their CVT's as well, so that you could hold a ratio when you wanted to. I'd be interested in that as well.
I don't think it's that much of a game changer though, Renli has sold a few machines like that, but they're nowhere near unseating the RZR as king of the offroad game, and to be honest, I think CF Moto is outselling them as well.
