i hope it happens sooner than later. i bought a logitech revue after the price drop (mostly to use the keyboard with my htpc)
ive been using it in my bedroom, where i use a media center extender. i like how it fills in a lot of the programming I cant get on the xbox without live (mostly hbo go, pandora, and netflix)
its media playing capabilities are a joke though, and the web browser feels like a beta test too.
one thing I think would be an ideal capability is a sling box type of function. you already have it plugged into your cable box, and also into the internet. just seems to make perfect sense.
