Well, I saw the video...Yeah...I prefer what we're getting with TFU. It might not be "real", but at least it looks like fun. The video wasnt that different than the original JK (without the mod). You just swing away while moving around, trying to hit the other guy. It's still very random.
I think it would be difficult to have, for example, the lightsaber combat from KotOR, in real time. I'm not saying it can't be done, because I don't really know, but I just think it would be difficult to come up with something good, a good system, that actually looks like lightsaber fighting....and no. That video was nowhere near the "real" thing. It sometimes looked like they were blocking some of the attacks, but no.
About LucasArts though, it's not that they couldn't, it's that they didn't want to. Sure, it may look silly when fighting a stormtrooper, but when fighting against a Jedi, it will look so much better than the video you posted. The characters will be doing actual moves and not swing around, randomly.
As for the ""new animation technology" they've been bragging about for the past year"...It's doing everything they said it would. They never said they could use it to create lightsaber combat as seen in the movies, or anything like that. The enemies are evading and are dodging and that's after they had to turn it down a little because the stormtroopers, at first, were really good and they could dodge pretty much everything.
