New Mac Pro was released only few weeks before holidays, as with pro users these timings don’t count. Also the mac mini isn’t what leads Apple (while more and more are buying it on refurb) and wasn’t updated during October’s update.
Then the new mac mini may be released at any time, and one forum user reported some information that may hint at an upcoming release in the following weeks, bringing Haswell and Iris graphics :
I work in an Apple Reseller and like many of you i’m waiting for the mini 2013 refresh.
From monday the two major Apple suppliers in Italy are suddenly and completely out of stock of minis. I know that this happen from time to time, but the timing is no coincidence.
Trust me, a new mini is coming next week, or at least we have solid evidence to believe it.
