Falhawk: I dunno, I may only have seen videos and screenshots and dev team yammering like the rest of you, but I have seen very few unsettling parallels between UT2K4 and T:V to date.
Besides the obvious fact that the Tribesmen have jetpacks whereas the Unreal grunts don't, the gameplay appears to be pretty much a dead ringer for a cleaned-up version of T1. The rocket pod seems to be pretty well balanced, with no sign of the bigger-gun-wins weapon progression of UT and similarly paced games. The maps seem very faithful to the T1 style with the added bonus of more trees (super yay!), and I highly doubt that the Buggy will prove anywhere near as ludicrously tough to kill as the MPB.
Also, I believe it is way, way, WAY too early to make the judgment call that "T:V = UT2K4 w/jetpacks!", considering as of yet the only movies we've seen are not of flag capping, of body blocking, of HO runs and other shit that really matters, but of random dev team members skiing and dueling in various pretty environments. Strictly speaking, we haven't seen any actual "game" play yet in terms of accomplishing gametype goals, performing familiar tasks save shooting the shit out of each other.
I for one will reserve my judgment for when I see with my own eyes how CTF/Ball/etc. actually behaves.
