I get it, and also I don't get it because I'm not a game developer. So I dunno how much you could estimate when something will be ready to go. Just seems people are going to be burnt out on all these little patches by the time the one with the maps shows up.
I get you guys probably want to release stuff as soon as it's ready because people have been impatiently waiting but...so what. People are always impatiently waiting for something. If they are impatiently waiting for your patch that just means people will be more excited when it finally hits. If you have absolutely no clue when something will be done then maybe wait until it's ready and just set a release date for one or two weeks later. Just enough for the buzz to build.
It's kind of a lose-lose situation, but imo it's better to get small patches with Invasion, gameplay fixes etc out when we can. There's no 'right answer' to be honest.
