Michael,
You forgot Vimy Ridge which you seemed particularly keen on elsewhere in this forum. If I was K&C I would be hard pressed to know what your preference is based on your various comments.
I am sure you will get plenty to choose from different brands over the period from now to 2018. Some you will like and some you wont. Just dont expect the producers to tell you or this forum their plans years ahead of time.
As he has mentioned in the first post Andy personally meets many collectors (and dealers) in many countries and gets feedback from many sources. At the end of the day people like yourself, Howard, Waynepoo, Doughboy, myself as a dealer etc will all have their individual preferences as to WWI subjects. I am not sure how you could establish a "significant consensus" based on your poll and recent multiple posts on the subject.
Whatever K&C decides to produce the one thing I do know is that it will be what Andy thinks will sell to the most people. How he gets to that decision is probably not going to be that easy. However you can also be sure that there will be those who think he chose the wrong subject(s).
Regards
Brett
