days waiting for a fix.
Now there's a healthy dose of optimism.
I don't know the details of this situation, if it is a genuine bug, if Adobe is aware of it, etc. But from experience, I do know that you're far more likely to be waiting months for a bug fix, not days.

Maybe Adobe needs to expand it's beta program before release.
Multicam edits switch angles when relaunching a project in Premiere CC (probably best to do multicam edits in CS6 for now)
Update 7-1-13: Adobe has posted a candid response to the multicam bugs.
