Cue,

Unless you have someone that has vision issues and needs the high-contrast LCD, then you really need to look at the 6XX line again, A 6XX will have the same functionality as a 520, more buttons, for about the same price (or less). I can tell simply from the availble picutre that the button layout and feel will be better on the 6XX remotes, and they are availabe now.

God knows when this remote will really be available. I get the feeling that its actually going to be quick this time, but the memory of the 880 rollout is still way too recent to discount.
