There's also a reference to another game; not sure if this is for summerfest or for some other event that will take place before the next patch:

Have you ever heard of Blitz Buffalo, kupo? It's a fast and frenzied buffalo-chasing fiasco ferried in from a land to the far west of Quon!
We moogles thought it sounded like fun! So we rounded up a bunch of buffalos and set them loose in several places, kupo!
Also, we've tied an item to each buffalo! Anyone who catches one can keep the item as a reward! It's a great opportunity for adventurers, kupo!
But the buffalos aren't going to take a bunch of frantic adventurers chasing them lightly! You may have to knock one out before it yields its precious item, kupo!
If you manage to lay your hands on a buffalo, you better prepare to be flung around, kupo... Kupohoho～.
Of course, it wouldn't be too good if you ended up being the one chased either, kupo! Just take care, and good luck, kupo!

That kinda sounds like what they did for the Christmas event two years ago where you had to chase down tree o.o

If that's the case then that event will totally kick ass =D
