The R32 would be the sportier option of the two I would think, the A3 3.2 being the refined cruiser/tourer. I'd be guessing that there will be a lot more modded new R32s than A3 3.2s if past trends are anything to go by.
I have no idea what this will do to sales of the A3 3.2, but they can only go down with a pretty much technically direct competitor. How many sales the MKV R32 steals from Audi is anyone's guess. If it looks like the photos that I've seen so far, I hope it isn't many, because it looks pretty hideous imho.
