There are 3 possible explanations for the design of the 2014 Mac Mini and none of them seem positive: 1) The 2014 is just a placeholder until Intel releases Broadwell or Sky Lake in 2015. Why buy a new Mini with an imminent improvement? 2) The 2014 is a lackluster improvement because Apple is planning on discontinuing it (eg iPod Classic). Why invest in an end-of-life product line? 3) The 2014 represents 2 years of Apple's best innovation, engineering and design. We know this is not the case because the new Mac Pro re-design was substantial.
