As to the first one... I have both, and like this one better. Not entirely sure if there is one reason for that, mostly perhaps because WITE, to me, pushed you to play historically as the Axis side, while not really pushing the other side to do it... I understood the reason for it, in WITE, but did not like the fact that you really had no choices. This game, encourages you to follow the historic pattern by the "High Command orders" which basically guide you along the path chosen historically, but you have the option, with some penalty in prestige points, to "draw your own plan" which is actually linked to the thing I like the most about this game, the independence of action, even if it comes with a price in-game. If High Command orders you to take Stalingrad, for example, by a specific date, then you either do it, and gain prestige points, or, you can "ask for more time" or, you can avoid it entirely. Following your own plan can have the effect of your being removed if your plans do not work, but if they do, you are not stuck by game code, as in WITE, where you are guaranteed that "High Command" makes, always, the same choices they did historically... you lose divisions throughout the game based on something that, in your "game universe" may not have even actually happened.
That said, the scale of this one is operational, and I somewhat like the WITE scale better, if they could just deal with their issues.
On the second part of your question, I am curious as well. I bought the first two together a few weeks ago, and really love the design, the card options, etc. I really look forward to what he does next.
