I think Sun Village was an intro almost to the Tartarus arc. I mean, it originally was meant to be Gray and Natsu going on the mission for Walrod... so o__O A hint at this arc perhaps?

Anyways, I'm hoping for another Erza arc... or, just specifically a JellalErza arc * ^ * It's not gunna happen, but I can hope it does X3

And I agree with the character focusses Mashima posted :) GMG maybe not so much. I wouldn't say Lucy was the main focus... there were quite a few characters imo: Rogue, Kagura, ULTEAR etc etc.
