They have been "ready to go" for quite some time. (Since 2009?) I'd go for it now and then get those things when they come out. It's not like you're getting the whole game to play through once... I guess.
Wait till Khaki is available and included. For some the black on dark blue CW units are a pain to read. (Talking ship names here). It won't be long. Just contact ADG and tell them what you want. I'm sure they will let you know when it's available. http://www.a-d-g.com.au/
