Don't the people who write these drives subscribe to Apple's developer program and get all the Mac OS X developer releases. They should have been testing drivers on each and every Snow Leopard pre-release over the last year. Then when SN finally ships it is a non-event as they been running on SN drivers for a year in-house.
What is it total incompetents or just being very cheap and not doing the work. They should have been running their beta test program in parallel with Apple's developer releases.
When they are this late now, I figure they will do it next time too. So I just don't buy their stuff. I choose a brand partly be watching their support and driver web pages.
