Generally speaking, it does seem they have decided to reduce the amount of content available per patch: we got 1 trial (just ex mode) and 2 dungeon (bad idea, 3 was working fine) when we used to have 3 dungeon and two modes per trial (HM and EX).
I enjoyed the MSQ as well. the story didn't stretch that far, but it was just like in 2.1 where the most exciting thing was learning about Minfilia's past and moving The Scions HQ from a city to another. Still, 3.1 MSQs were far more exciting than 2.1
If they keep with this pace, I wouldn't expect new MSQs until 3.2 and probably we won't get tons of them ...
