I sure hope they put a 4s in the Rush, that's what I'm waiting for. I haven't heard anything yet about next year, it's too early. If not, I will be on a 2s Rush next year and try it out for a few years. I for one think Polaris is back on the right track starting with the new mountain sled. They seem to have really done that sled right! Every single review I have read says it's the new standard for mountain sleds. Now they will move on to other segments.
I'm not too worried about Polaris getting out of the snowmobile biz! I remember about 4 years ago a post on here that Polaris was for sure leaving the market in 3 years. Well, that's going on 2 years ago and they are still around.
