As far as that slew of content goes, there's no way they're going to put that all in one update (nor should they, really). I would imagine some of the stuff gets delayed for a follow-up update which will happen about a month after the next major update. I mean I'm sure they have some of this stuff ready (they've been working on play-as-a-monster and Mog Gardens forever), but from their point of view it would make the most sense to space out content so that they are releasing new stuff regularly to keep people interested rather than slamming us with a boatload of content and then having people complain about the lack of updates two months later.
I think the most likely candidate for delay is probably Skirmish II. New areas/Naakuals/missions all go hand-in-hand, and I think it's pretty important to get the GEO/RUN stuff in the game so people feel those jobs are progressing as well.
