AA didn't add anything new for a reason, they were able to make the entire campaign using units already in the game with some new voice acting sprinkled in.
Relic has been like this ever since. Nothing unusual.
They are hiring people to work on DoW3, they are not hiring people to work on CoH2. There is 0 reason for them to continue to support CoH2 when they can release DoW3 and make more in a week then CoH2 has made since it came out.
Their wishy washy attitude towards talking about what they are working on it's just conformation that they don't think they are able to keep content rolling for CoH2 and work on DoW3.
Except that they are constantly saying they are working on a warspoils overhaul, amongst other things.
Except they refuse to talk about any of the development going into those things "We are working on it, maybe" is code word for "We will get around to it whenever".
They specifically said there wasn't going to be any new content in the march 31st patch. And they are working on DoW3 now.
False.
They haven't announced anything and they refuse to talk about what's being worked on because they know if they just told everyone "Were done with COH2, sorry" the entire community would just throw it's hands up in the air and quit.
