From everything I see and hear says you wait and see. Watch for new growth come spring before pruning as one you might stimulate new grow or prune too much.

Yes, you should wait. If you cut them now and have a hard freeze, it will die back from the point where it's cut back. Leaving it will keep that from happening, since it's already frozen back. And Wally's right, you don't want to encourage new growth when it's warm because you could still get a freeze.
