Consider the Tegra, Android, and Windows Mobile 7, all coming around the same time frame and all compelling factors (I think). Tegra's battery life and visuals are just ridiculous, and Android's interface elements are shaping up very nicely. I personally have the same dilemma - got my Touch 6 months ago, but I'm waiting for any of the aforementioned and passing on the Diamond/Raphael.
