The ability to battle with your friends on Wi-Fi would've made FFTA2 INFINITELY more playable. God knows why they didn't bother with it :T (well, it was supposed to be a GBA title at first, but still)
That said, this makes me very happy. I hope they seal the deal by letting you name your Pokemon units as well; but even with just this, I'd very much like to play this title. =D
