Will Unreal Tornament 3 require a PhysX card?

I've heard Ageia's card is pretty much worthless at this stage due to lack of games support and any noticable difference in gameplay (with the exception of cellfactor), but i was wondering:
Will it be a requirement for UT3 or will it just be supported like GRAW and other titles?

I'm reluctant to get one, but if it is required and is noticably beneficial, I may reconsider.

Hope this hasn't already been asked. If so, then I apoligise already,

Thx for the replies. I'll just wait for it to come out and see what the benchmarks on it prove.

Already running a pretty decent card (GTX), just gotta wait and see.

Just thought I'd ask as I tried to run Cellfactor on my rig without the card the other day. It didn't run too bad, though when cloth was enabled, the frames just dropped like lead, lol.
