has that feature been confirmed? assuming yes it will be interesting so see how the mainstream reacts to it. personally i couldn't care less, i have multiple tvs .. one for tv and one for games, both can do netflix/movies. also remember, the "streaming" controller won't be for motion games meaning a lot of the "expanded" audience won't care for it.
and as nintendo fans have always told me -- it is all about the games. third party support that is mostly ports of ps360 games isn't very compelling either.
