Combating system obsoletism

[topspeed]

Hey guys, I'd like your opinion on my current quandry.

As many of you know, I finally stepped up to HDTV and am receiving my JVC D-ILA set tomorrow. While I feel I can hold my own on the audio side, the video side is a whole new world to me. What I've found is the new set is the first in a chain of upgrade dominoes. Naturally, I'll be upgrading the Dish stb to a HD capable stb w/ dvr. While I'm not crazy about the price (around $1k), cable is really expensive here so I'll stick with Dish.

That's the easy part.

Now originally, I'd always envisioned getting a universal player to upgrade my antiquated Sony DVD player, which is neither progressive scan nor has DTS. However, there are two factors that are making me reconsider this course:
1) I'm not sure SACD/DVD-A is going to be around long enough to make an investment in.
2) The emergence of HD-DVD and BluRay

Based on what we know, should I buy a nice universal like a Denon 2910 and enjoy the limited library of hi-rez available (this would somewhat justify my overexuberance when buying surround speakers and satisfy my "music first" mentality) or buy a far less expensive prog scan dvd player (~ $200) that has great video capabilities as a stop-gap until the HD-DVD/BluRay debacle works itself out? What would you buy for $200-300? The JVC is 720p native so should I even worry about the new HD formats in the first place?

This is all very confusing to me so I appreciate your input.
