Actually there is a 1080p set that can accept a 1920x1080 signal. The new HP DLP. It got a good review too.

The problem for me is that they only come in 58'' and 65'' versions which is too big for my apartment (and too big for my wallet). I will wait until next year when a 50'' 1080p actually accepts a 1080p signal.
