Didn't anyone noticed that there was no macmini server in the list. This means probably the macmini will get a redesign.
I did notice, but unsure how you interpret the server omission as evidence of a Mac mini redesign. The current Mac mini Server is nothing more than a Mac Mini w/ additional storage and Server OS. Apple could easily axe the Mac mini Server variation as a stock model and make it CTO only w/o the "server" model moniker.
I doubt Apple sells that many Mac mini Servers to make a stock model viable, but still profitable enough to make it CTO. The Server OS still lives on w/ a Yosemite variety, so Apple still needs a small box for it, as an MP is overkill for many of Server's uses.
