Edit: Here's an RS:

How much bigger will the 6 be versus the 4? I remember driving the pain old A6 and A4 back in the day, and thinking the A6 was boring to drive and the A4 a lot more fun. Not sure what the RS factor brings to the table, other than power. I do like that it apparently is a bit shorter than the Mercedes wagon, which is a tad too big for my tastes. Something in between the most recent 3 wagon and the Mercedes in size would be perfect.
