You mean, just like Civ VI?
My take is that a lot of the problems with the OpenDev versions were balance issues based largely on numbers and factors, and those are the easiest things to change in a computer. I would strongly suspect that since the last revealed version there have been several 'balance passes' of those numbers. Remember, they have a NDA-confined group of "VIP" testers that apparently are there to do little else but test such things and provide "internal" feedback to supplement what they got from trhe OpenDev games.
Now, as posted above, I am not saying I expect everything to be completely balanced and Perfect on Release - just the myriad combinations of Factions have too many variations to be completely tested, unless they have a small city's worth of Beta Testers beavering away at it, so I'm sure we'll see some Howlers that slipped through.
