According to MacRumors' historical data of the number of days between previous Mac Mini releases, these would be the most likely release dates: Earliest: 2015 (June 11) Most Likely: 2016 (January 4) Latest: 2016 (October 15) The "earliest" date is based on the shortest time between releases (231 days). The "most likely" date is based on the average time between releases (438 days). And, the latest date is based on the longest time between releases (the current 723 days between the 2012 and the 2014 models). There is no doubt in my mind that Apple will not release a Mac Mini Broadwell before releasing an iMac Broadwell. The chances of them releasing a Mac Mini Broadwell in Q1 or Q2 of next year seems pretty slim, since they just did a refresh, last week.
