Official sketches of the Audi A5 Cabrio, A7 and A8 of the future?

Here's a slew of renders supposedly reported as "Audi's official leak". Well, I couldn't agree much as one states 'Chris/06' as for the so-called A7 render (With an A5 head) follows largely the REAL 'OFFICIAL RENDER' I reported earlier on. Worth noting is the A5 cabriolet, which shows a render that's even worst than my imagination and a photochop image reported earlier on. As for the A8 render, it's really far off from the A8 I reported earlier on that's been somewhat confirmed from my 'interrogations' with an Audi staff.
