While I'd prefer the wagon, the sedan is not a deal breaker for me in the slightest. What would be a deal breaker is having to wait until calendar year 2014 to buy one, along with the inability to spec a manual transmission.
Ideally I'm hoping we get a manual+quattro configuration. Frankly, I can do without a lot of the electronic gadgetry (lane monitoring, Drive Select, etc.), just give me a decently power bumped 2.0T quattro (220hp perhaps?) and I'll be happy as a clam.
