The word was that the biggest saws were going to be around for a while because they sell the fewest of them, and apparently stihl banked up tons of credits with all their 4-mix stuff, though apparently the credit system was going to go away sometime too?
It seems like the cutoff for all these saws is nowhere near as abrupt as everyone touted it to be in 2008 and 2009.
It's unclear to me if they will even replace the 460. I think people said it was going to happen though, and that it would probably be very similar to a 441. The strato version of a 660 sounds pretty sweet to me though!
I ran a 211 that I picked up for cheap on CL for a little while yesterday. That saw has some balls for a little saw. Cut through some 8" maple very well, pulled the chain strong. It's going to be an awesome little brush saw for stuff my fs 450 cannot get through with the scratcher tooth blade.
