I'd bet serious money that they won't - sorry.
They've always dragged their heels producing cradles for the latest models of phones - even before smartphones arrived they only tended to produce them for the most popular few models of each manufacturer's range. I had a cradle for my old Nokia 6230i and, when I switched to an HTC Desire, there was obviously no cradle available. Whilst I could still use the phone via bluetooth, I really missed the cradle as it gave the convenience of somewhere to stash the phone whilst charging it and connecting it to the sharkfin aerial for better reception.
Have switched to an iPhone now and laid out for the cradle for that (£100+!!!) but it's worth it to have the convenience back. As far as I'm aware, they decided to do iPhone cradles due to the sheer ubiquity of the things but haven't bothered with any other smartphones at all.
From what I can tell from the newer models, Audi are ditching the cradles altogether in favour of pure bluetooth, with the option of RSAP connectivity in the higher-end preps. It's obviously just too much hassle trying to keep up with all the latest models of phone, especially when most people aren't interested and are happy with basic bluetooth connectivity.
