New means for me, it needs 4 month shakedown cruise and OS updates to iron ouut hardware and software bugs.
I bought rMB two weeks ago, I needed something now and even March announcement wasn't something I could bank on shipping for weeks or until WWDC time frame.
Also, my 2015 12" Apple Special had to be brand new - clearing out stock, perfect condition, $1099 or B&H has stock new units $999.
I might pass mine to someone and buy 2016 in October if it is significantly better - unlikely as I don't see any weakness now.
