As a recent RS4 owner, I almost cancelled my E92 order after reading this...although would've prolly gone with the RS5.
Having played extensively with both manufacturers, I think it can be summed up pretty simply: BMW is built to drive whereas Audi is built to enjoy. So if you're like me and you want to enjoy your drive (hehe..) you can find yourself on the fence. I'll prolly go back to an RS something in a year or so.
