We wrote just last week that Apple was likely prepping a refresh for some of its lineup. TheMac Pro, iMac, and MacBook Air seem ripe for revision, and few “unavailable” notifications at the Apple Store seem to confirm it.

It’s not a full-blown “no more!” — really, it’s just a hint — but it does indicate that Apple stores are getting to the end of their Mac Pro stocks. If they aren’t getting resupplied, you know what that means.
