I am eagerly waiting to receive my copy to decide if the subject interests me enough to pre-order the second game in the series. I may be in the minority, but the pre-1939 wars interest me more than those in the 1950's and later.
One thing worth nothing is that Jay's designs include many smaller scenarios which make his games a good entry point in the series and a good choice for those who have limited time. I recently brought Marianas on a business trip and while I generally prefer large scenarios, I was able to enjoy three evenings playing short scenarios in the hotel.
