Yeah, but the physical size of the television at 21:9 is just silly. And that's why it'll never catch on, people like their televisions at the current wide-screen 16:9 dimensions, anything with an even more exaggerated rectangular shape and it'll be almost to wonky for most current rooms/decor.
I could see 21:9 projectors becoming a standard though, for people with truly high-end home theater rooms.
