I only updated my projector to go HD. This one is a "disposable" one, as I intend to buy a better one in a year or so when the "good stuff" is available. I think "good" projectors are just now getting to market.
So I'm about $3k into hardware right now.
I own about 50 HD-DVDs I guess. So maybe $1200.
However I just moved and my new theater room is a major different beast. The dedicated room is 18' x 27' and I'm building the entire thing out from scratch. Right now I'm down to the bare frame as I'm re-doing all the drywall, electrical and so-forth. I'll probably end up spending about $40k on it in the next few months. All the new equipment will obviously be based on future HD standards in mind.
