It may well be that there are no updates scheduled for/available in the non-oss repository, but this doesn't reflect reality. Adobe has released an update for their Flash Player to version 11.2.202.310 appr. a week ago. Not that I like using flash, but unfortunately a lot of sites out there in the Internet still require it and I'd therefore prefer to get such updates in time, even for proprietary software. FWIW, other distributions have already published corresponding updates.
