The new version of the trailer is very nice. It's a minute shorter as it misses the intro where Snake and Campbell talk about Outer Heaven (although you'll notice the introductory song beginning is uncut), but it's more than worth it compared to the previous version.
There's no new footage, but the noticeable changes are:
1) Smooth framerate all the time.
2) Particle effects are greatly improved. Whether it's sparks or rubble, whenever a Gekkou breaks something, there's a thick cloud of small stones and dust. Smoke is more prominent too.
3) Motion blur. I think it's excessive sometimes, but whatever.
4) Some very slight angle changes. For instance, when Snake picks up his cigarette. I can't say I noticed any others though.
