With regard to 1080P, yes, I think it will support most requirements for some time. One important thing to note is that resolution is not the only factor that determines visual quality. A review one of the major electronics info websites did recently came to the basic conclusion that it is very difficult to tell resolutions apart, even when one steps down to the 1366x768 sets, and that other factors such as black levels and color quality are much more noticeable. Also be sure to consider other basics including whether the TV has the right ports on it for what you want to do.
I have a relatively cheap LCD that I bought recently (just after Thanksgiving) but I love it so much. I'm watching a DVD on it and it's really gorgeous. 🙂
