That quote from the former employee complaining about the "old guard" resistant to "new ideas" seems worrying to me
We all know what such "new ideas" took the direction of DoW3 and gave us a poor MOBA clone. Hopefully Sega keep the CoH formula and these newbies don't turn the series we love into a WW2 themed clone of whatever is flavor of the month like battlefield did with battle royal.
As such "new ideas" in corporate speech is looking at what makes the most money in the market and trying to get a cut of that action by copying it and screwing as many of your returning players as possible.
I'm actually really worried about CoH3, coh2 was a complete mess with DLC on release. SEGA have been messing up total war for a while now too
instead of focusing on new idea they could improve on old ones , make front rear and side armor, make flanking more rewarding, make ability more engaging (planes) , add more factions and units type , destructive environment like iron harvest, etc
