Heinen's in Osseo, MN has Nytro RTX's for $8999 right now - all colors. No set up or delivery charge - just a $50 document fee. I'd be surprized if you will see any better price for quite a while. Yamaha's current incentives end 12-31, so the January price will likely be higher unless they come up with a new incentive because of slow sales and that doesn't seem to be the case with the early snow. Prices did go up last year in January when I bought a Phazer FX from them. I wanted to buy a 2nd Phazer in March-April, but the prices were higher than in January and this dealer was sold out in late January.
I'd say there's not too much price movement left until next fall 2008 when the big incentives come back on carryovers.
Every spring, for the past few years, I drive by dealers in MN and see crates of carryover Polaris'. Very common. Similar situation some years with Cat dealers. Each fall, lots of MN dealers blow out 1 and 2 year old carryover Poos and Cats. That doesn't seem to be the case with Yamahas, and especially with popular new ones like the Nytro.
For example - I was at a small Yamaha dealer in the Minneapolis area two weeks ago and he had 4 Nytros on the floor - that's all he had ordered. I went back a week later, to see if he would be dealing on price - and he only had one left. Guess that answered my question.
