We will definately have a Star Destroyer because of this statement alone:
"In the end, we decided these ships were simply too iconic and exciting to ignore, and we invented a new “relative” scale..."
I've seen people try to make this claim before. But it's about as valid as saying they won't make one because my left sock is black... the relative scale allowed them to break with the 1/270 scale used for star ships. It does not mean that they're working on ISD's.
What you have here is the Association fallacy. The fact that they were willing to break scale to put in a GR-75 and CR-90 is not proof that they're working on a ISD. Keep in mind, up to that point we didn't think they'd ever include anything larger then the YT-1300 because they said they wouldn't.
The reasons why a ISD isn't feasible for this game have been gone over and over again in this thread alone.
