I don't know of any 720p HDTV sets that don't do 1080i. Didn't HDTV start with 1080i resolutions so most every HDTV out there will have 1080i??
You can find a HDTV with no 720P, but I don't think you can find one that doesn't do 1080i so blu-ray will still play at HDTV for almost all HDTV owners out there
