The prices on the 800 are dropping significantly recently. I'm thinking that's a sign of the 900 coming soon but its just a guess (kind of like apple dropping prices ahead of upcoming new products to clear inventory). That in itself might be incentive to get the 800 and save a few hundred. I think the 900 will be improved sound wise and feature wise based on the changes between the 1000 and 1100 but I doubt the changes will be too monumental to not enjoy an 800 NOW rather than wait for something that may take a while to get to market anyway. I e-mailed yamaha about the 900 and the seemingly canned response was the 900 wasn't scheduled for US release anytime soon, please look at the 800 instead. That was december though.
