Just wondering if the software (OS) of these new and "old" 770 are compatible (propably not?), and if the 770 support will stop in favor of this 870, as it was called in earlier post? Does this mean that I should sell my 770 now on eBay before they become "obsolete"? In order to do that I need to know before "general public"...

Anybody have any idea when this would become available? I think that they should target for this Holiday season... and what would be the sale price?
