I find it very hard to believe that so many dragons (10000 according to both future Lucy and future Rogue) could go unnoticed for so long. Even before the year 777 dragons were supposed to be very rare, even to the point that 7 years after their total disappearance many people believed that dragons never really existed and that they are just fables.

Thus I wouldn't be surpised if the draongs that attack Fiore are actually coming through the eclipse time gate from the past. That would also explain what the future rogue is trying to do. Since opening a gate to the past will bring the dragon army into the present, he wanted to change eclipse into a cannon to take down Ancalogia and/or Zeref in the present.... Though that still doesn't explain why he fought Gajeel.... maybe just for fun or to teach either the present Rogue or Gajeel some new tricks that will be usefull in the coming battle.

Something else I'm pretty sure about is that something bad is going to happen to at least one of the Lucies (Death or Coma) otherwise the whole part with Levy writing the story down on Lucies behalf wouldn't make sense.
