Ours has it, but we can't use it! Aaargh! Paid extra for it but can't take advantage of it right now.
So it might not have been a good move, particularly since prices are dropping so fast. It might also be a better strategy to wait a year when Blu-ray DVD players have come down in price a bit.
In our case, we couldn't wait on the tv since our old tv gave out on us and we needed to replace it right away.
I've read that within a year Blu-ray players should be available for around $500 vs. paying $1000-$1500 when they first hit store shelves later this month (perhaps later this month, perhaps next month).
Yes, Sony is one of the first to step up recently and offer true 1080p processing (ie can accept 1080 on the HDMI input) in many of its higher end sets. Man, the price on those Sony SXRD rear projectors has really come down quite a bit. That's a nice set that you selected there, and I don't think you'll regret it. And you're well prepared for the future with two HDMI inputs (as DRM becomes more pervasive, they may be the only way to get HD sources into your TV, so you've got one each for digital cable/satelite, and one for DVD) - kewl!
HD-DVD has been out for a couple months already and may have some advantages (mostly in terms of disc production cost) over Blu-Ray. HD-DVD movies are already available. I have an XBox360 and Microsoft is releasing an add-on HD-DVD drive for it that I may get, depending on price. But I wouldn't rush to buy either of them just yet - movie selection in those formats is still pretty poor. And honestly, while HD is great, plain 'ol 480p (widescreen anamorphic) DVDs still look pretty good, as I'm sure you're aware.
