Plan to add a projector with drop down screen to a basement family/media room. Going to put a plasma on the wall for now (and for TV during day with windows open), so not in huge rush, but, hey, life is short so sooner is always better. Anyhow, wondering if for the projector, as it will be larger, if 1080 is the way to go and, if so, it is really worth waiting a bit for prices to fall, especially if I've got the plasma (720) for the time being?
