As we've argued about in years past, it's not just cameras. There's a lot more infrastructure and computer power and hard drive space needed for HD over SD. Even rolling your eyes at that, the editing/rendering time may be a constraint for HD over SD on a show with such a quick turnaround. Who knows what the bottom line is with CBS?
If Big Brother UK can do HD (they began last year), the US should be able to do it.
