He did say something to that effect: basically he doesn't want GVs in the strat towns. I think the design of the ack in strat towns supports that. There's tons of ack everywhere and I swear the hardness of them is much higher than field ack. I took a tank to the strat town (had to drive around in that vast neat eye candy) and the ack took nearly infinite HE hits without going down while field ack will go down if you sneeze in its general direction.
