Unfortunately it isn't possible to receive prior notification. When a security update like this is being crafted, it has to be done in utmost secrecy to avoid exposing the vulnerability. The security team doesn't even expose the fact that they are working on an update as far as I know. But even if they did, it would be difficult for them to give an estimated release date. They want to get the update out as soon as possible, for obvious reasons; but they also don't know how long it will take for them to fix it and test the fix.
