Unity's pricing change! Will it affect GoW?

The only people to answer this question do not read here and even less leave comments. If they are planning an engine switch, we’ll get to know in time. And then have to sit through half a year of bugfixes.
I’m still unsure, if this game even makes enough money per year to be obliged to pay per installation.

By the way, there’s already a little thread going about the subject.
