Maybe, maybe not, LB. Its all just rumor right now.
Im glad to see more manufacturers than just Yamaha working on building better 4-strokes. Competition is good for everyone because it forces the OEMs to constantly work to one-up each other.
I dont think you will see Doo get serious about 4-strokes untill about 2010 (I dont see the SDIs being able to make it past 2012 emission regs), but I think you will see Polaris and Cat with new 4-strokes.
Cat has their Suzuki affiliation, so they could match Yamaha in sportbike engine technology. Polaris seems set on the Weber engines (which are good engines), so we'll see...

With as much time and effort Polaris spent on fixing the fussin 900 and developing the 600 & 700 versions they did not have money to put into the Turbo 4 stroke. They modified the existing engine from the defunct water craft division. the motor wasw built to cool by fresh water intake and not a closed loop heat exchanger system and the power HP vs torque are nowhere near the normally aspirated yammy. The water craft engine is not a stump puller and was built for high rpm ripping.
A water craft is fairly slippery with little resistance leaving the line. A snowmobile however is a different story. Breaking the inertia of a still sled to full blast forward movement takes torque plus the load created by the solid hookup of a studded track creates even more load. All told if it is turboed and still only making mediocre HP and torque I see no possibilty of making this a blaster capable of running with 4 yr old yamaha technology.
this is a tourer to make the govt happy at Yellowstone and a desperate lunge at stopping the hemorage of Polaris faithfull from jumping ship to the 4 stroke king.
I think all it will do is send more people packing.
I'd be willing to run title for title.

Yamadog, it takes a lot of torque to get a watercraft up on plane.
The last pwc I rode (last year) never came close to ripping my hands off the handle bars. I just dont feel that a motor that spins a jet drive and pushes against fluid for propultion has the same load on it that a sled or any machine that has positive traction lock with an imovable surface such as the ice hooked up to the studs on your track.
