I agree with Darko, the only reason I have a Ski-Doo is that the M-chassis is not far enough forward for me and feels "old-school". I would trade in the Ski-Doo in an instant for a true rider forward M-Series sled.
That being said, for what its worth the AC rep at the spring show told me no new mountain chassis next year, but they are working on a new trail chassis for 2010.
That would be more believeable. They always come out with the new trail chassis before the mountain chassis. Its pretty much economics, they sell waaaay more trail sleds thats where their going to put the $$$ for new iron; at least to start with.
