If they do announce a minor spec bump or price drop for the rMBP at WWDC when would they likely announce it?
Would it be at the keynote on Monday or during the week at one of the other presentations?
Agreed. If nothing is said at WWDC in a few hours, then check the Apple store to see what has been updated. Plus any new models may be at the Apple stores by tomorrow morning, if not later today depending on your time zone.
