TP's point is that Sram Red 22 has, quite literally, just been announced to the press, in person
less than ten days ago.
It may not hit the public market for a few months.
Many may not receive their own order for quite a few months after that, as priority will be for OEM sales (as it always is, always was, and always will be).
So, to continue TP's tip of the hat, first hand experiences with 22 may not come for a while, and if you want to wait until you get it in your hands you may not be riding that frame for quite some time.
Alternatively, ride what you have now and switch groups later. If you can't wait, DA 9000 is pretty awesome in its own right, as one would expect it to be. I really don't see 22 possibly disappointing if you're already in favor of SRAM's approach (loud, definite shifting, double-tap, etc:.), and obviously there is more tuning surrounding SRAM than there is Shimano at the moment. It just seems that people are more willing to take the knife to a Red group than a Dura-Ace or Super Record. Anyway, it really doesn't matter too much: ride what you want, swap whenever you want.
Ah, the beauty of a bicycle: where you are the engine, drivetrains are not proprietary to the frame, and components are (mostly) interchangeable.
