Actually I think CMx2 is awesome as is, it can be a whole lot more with an op layer. My comments were in response to what kino mentioned.
For me I just do not like the late war stuff (late 44 to the end), never have.
Having said that, I will be getting the CMFI module to complete that set, not sure what year that will cover?? Just like I will support CMBN and CMRT additions. When it comes to CMFB and a CMBerlin, not my cup of tea.
