Looks like someone's leaked some shots of the 8V A3 Cabriolet:
Are You The 2015 Audi A3 Cabriolet?
It does kinda look exactly like I expected... an 8V without it's roof!
This article states 2015 release, but it seems the US gets the new A3 after the rest of Europe anyway, so it might not be that far off release over here. They can't confirm these are official photos, so they could be renderings still, but I'd put money on that being pretty accurate.
