I am slowly starting to build up hype about this too, I actually bought Combined Arms years ago in the hope that carriers, or other ships, would become playable/steerable one day (you can already give movement orders to ships in CA). If it would require the purchase of a separate carrier module, then I would buy it.
Only catch is what ships would be playable, is the Admiral Kuznetsov still on the cards? I am more of a Su-33 + Kuznetsov guy myself.
As far as I gather, the Kuznetsov will only come later after the module's release. I don't mind waiting a bit longer, but please don't neglect the non-US side, it's not often that games allow you to play as a side other than the US so it's nice to have something different for a change.
Please give the old gal some love too! Making the current Kuznetsov model steerable for the module's release would be great. All the other carrier functions can come later.
