I expect the Guild to be totally reunited as if nothing happened in 3 chapters tops without us learning, to any great extent, what everyone's been up to for the year, if they've been up to anything that is. It's only been a year, after all, and unlike OP's timeskip where every member was thrust headlong into unique circumstances and had to deal with them, in FT they're just told to go do something else just because.
What I hope for is that Natsu and Lucy go on a long journey, taking up jobs and interesting adventures (which allow us to explore the world, even if only a little) where they gradually reunite with the members, forge ever stronger bonds while the plot moves towards the Zeref/Acnologia encounter. YEAH RIGHT
