Why are people still talking like this is speculation? There was never going to be a factory boosted option, I think some are confused. There also isnt going to be a new brochure released to announce it. Dealers all just attended the big dealer meeting where they order the sleds for the coming season, if it wasnt an option then it wont be until atleast 2011.
Look, there are the words straight from Ski-Doo...
"Summit 1200 4-TEC Cancelled
After feedback from dealer forums and BRP internal staff, the Summit 1200 4-TEC models have been cancelled for 2010. Despite having the best 4-stroke power-to-weight ratio ever achieved in the Mountain market, we still felt that the machine did not meet our high performance expectations."
