First comes the A7, with choice of four door "coupe" -- or four door convertible! Later comes the RS7, although I doubt that will be offered in convertible form.
Interestingly, and somewhat confusingly, they talk about the RS7 having the V10 from the (next) RS6 in this article, even though Audi has yet to announce availability of the next RS6 -- not just here but in Europe too. Or did I miss something?
