Re: Larger sizes ?
My understanding is that the materials, processes and chemicals are different. You'd have to revalidate everything... and if you are going revalidate everything anyway, you might as well just change your design to 28nm while you're at it (by change your design, we're mostly talking about a drop-down in the options menu).
I'm assuming that 28nm fab capacity being "available" is a well known thing. Maybe people are suspicious that if even a few customers switched to that, it would be as unavailable as the other node sizes...
