Since more than 90% of the HDTV sets that would come out this year will have HDMI 1.3, then this won't be a problem.
For Plasma:
Refer to Pioneer 8th Generation of Plasma TV sets.
For LCD:
I suggest you wait for Sony/Samsung to activate their 8G LCD plant. Once there, the TVs should start arriving within H2 of this year.
Or if not, go with the new Sharp Aquos line (8thgen panel)
Forget about LG Philips. They SUCK as the only purpose is for budget.
Syntax or Olevia by Kolin are budget TV sets. The Taiwanese sets have low prices but only average quality (unlike the big guns)
Let's see what else...
Oh yeah. If you are not in a hurry and can wait for a year or so, why not go for OLED TV.
By 1st gen release, it would already have AT LEAST 1,000,000: CR, 120hz refresh rate support as standard and ultra-fast response time of less than 1 ms (or speeds is MICROSECONDS).
Pick OLED over SED. Don't pick SED if Toshiba still runs the "show"
And yeah aside from that, skip projection technology (front and rear)
That's all the advice that I can give you.
