OK, that's new... Android - Google updated to v1.1.30003 already, while Steam is still at v1.1.29009. (and the itunes webpage also already lists v1.1.30)
It looks like server v1.1.29009 supports both client versions, so no raid disruptions from this update.
Assuming Apple doesn't allow 2 updates for the same app in the queue at the same time, I guess the september update is at least 2 weeks away.
(oops, didn't notice I'm answering in the news and announcements section...)
