It appears that PP is no longer offering the HC720 as it is not listed on their site anymore.
Having only one hdmi port is a non issue for me and I would presume a lot of folks. If I need more then I will buy a switcher, there cheap and keeps me from having to replace my receiver. Besides I'm not so lazy that I cant get up to manually do it, pain though it may be.

1080p is also a non issue as I do not have an HD/BD player nor the intention of getting one until everyone decides to get along and choose a format. The only HD source, if you can call it that, will be my 360. Of which will be set for 720p anyway. Besides 1080 i/p will have to be scaled to 720 anyway so I can hardly see how there will be a noticeable/discernible difference in picture quality.
Other features and issues however are another story. Leading me to a difficult decision.
Also .. I'm curious to know why theres not as much buzz about this projector as there has been with other recent listings?
