We've decided that the best way to deliver the UT3 expansion we've been hinting about is in two parts. This patch is the first part. We aren’t quite ready yet to start going into detail about the bonus content and gametypes that will be in the Titan Pack, which is substantially bigger than any bonus pack we've released in the past.
This implies that this could be more of a bonus pack for those who've purchased the game, and could also be the foundation of a repackaged UT3 (all the fixes and bonus content) ala UT: GOTY edition?
Either way, this is pretty cool.
