Rumor: BlackBerry PlayBook OS 1.0.8 Coming in September?!?

Well here is a bit of interesting news. It appears the the BlackBerry PlayBook will have to wait until September to get the next OS updated to v1.0.8. This make me wonder what happened to late summer? The details on this OS update are not clear at this time. Will this update include native e-mail, PIM and the Android App Player? Who knows at this point? What is your take on the September OS update?
