gadgetrants, I think ICS will still fullfill at least that basic promise: It will be the one codebase to program for, for phone, tablet, and TV. Beyond that though, it probably won't bring much to the table.
Still, I wish they'd actually take a longer time for major OS versions, so they can actually implement all the planned features, and do it right, rather than creating some line of BS (Honeycomb isn't "complete" so we don't get the source? BS!). Of course, bug and security fixes should be pushed out for more rapidly than they have been.
