In that case I can imagine they, for instance, may have to create an entire new collision framework around the level just for the Ripper projectiles.

IMO dodgejumps completely killed UT as we knew it. (reasons for this have been stated hundreds of times in the past)
So therefor I hope it won't return. Ever.
the gameplay ut3 is based in avoids dodge jumps,
if they add the dodge jumps, then is not an ut3 expansion, its a different game.
