Sort of inbetween
I think the problem is that 28nm right now is sort of nowheresville when it comes to fab nodes. A lot of the currently in use designs for microcontrollers and the like use older nodes like 30-ish and up from what I can see as that is what previously was available cheaply, while the current state of the art for (phone) CPUs has moved on to lower nodes (probably 14nm and down). As fab capacity in the 28nm node becomes available (and cheap) we'll probably see a lot more chips designed on that node to fill up the available capacity.
