I think it will be ok but they better have their motor problems solved. I used to love polaris but have watched way to many of their new intro's flop hard. Sleds such as the Ultra, the XCR's the RMK 900 to name a few.
Was able to test ride a 2011 Pro RMK in Revelstoke this past Wednesday (March 3rd)
My overall impression is that this sled is going to be very well received and sought after in the coming season and following years. It is everything the video in the first post says it is.
