I agree but I believe the article is talking about how in Total War you go from the turn based campaign to the real time battles.
I think some of the Wargame entries had a similar turn-based campaign, but it was definitely
very simple, even compared to Total War's strategy element which is also pretty darn simple compared to other titles, or just Total War's real-time battles themselves.
The article definitely made SD2's map sound a lot more expansive compared to the aforementioned previous Wargame entries, but I would say to hold out for more info if you're real curious about the strategic side - doesn't seem to be anything truly concrete on how that'll play by my estimate.
