A bit tangential, but I really hope some service solves the "couch potato" use case for streaming - I love Netflix, but I miss cable tv's channel jumping.

I want someone to curate and select shows for me, and show them in a channel, so I can just browse (an improved Cable Tv experiencie, hopefully ad-free, but probably not :P ).

I also miss live (or slightly delayed but current) sports - that would be a killer feature for Netflix.
