My update has been "waiting for review" for a week. I'm going to just let it proceed. When the update goes live I'll test it and if it's corrupted I'll just remove it from sale. Hopefully this will prevent users from updating. Then I'll email support and wait until the issue is resolved.

Don't play games with this one. If I were in your shoes, I'd pull my binary, too.

You do not want to be waiting on the App Store Review team to fix this. I'm one of the developers in Marco's post; it's been 24 hours and all I've gotten is a boilerplate response from the App Review team.

Funnily enough, updates can still be received if an app is removed from sale or even deleted by the developer.

I think you are right. Was just browsing the app store and seeing a number of apps getting 1-star reviews because of recent updates.
