When I was at Northeast Stihl last year, I asked he head of product development for Stihl-USA about this.
There will be new saws coming, soon. The 362, 661, 461, etc etc.
The 200T will be phased out but not until 2011 or so. This will be the last saw they mess with and will be sure it comes back better than it is now.
They will also be releasing a new climbing saw next year to compete with Shindaiwa, and Redmax new climbing saw. The entire saw will be small enough to fit in the "frame" of a 192T!!! It will be called the ultra light or something to that effect.
They did good with the 441, so hopefully they will do right with the new pro saws. They will also be testing the new electronic carbs, while Husky will have its fuel injected saws out by summer/fall.
