I'm glad that WWII will be the follow up title to take advantage of what BFC learns with the first title. They have said many times that several of the cool features we want will make it in to CMx2, but not for the first game. I see the WWII game as taking advantage of a more fully developed version of the CMx2 engine. It's really what I had hoped for all along.
While I am not a fan of modern combat, I don't think I've played a really good modern combat game on the CM scale, if one even exists. But I am sure I will like it and the Tesla Coils will kick ass!
