They are adding Tifa, Rinoa, Auron, AND Balthier!!! O.O
They're adding characters that I REALLY like! Well Tifa much less than the others but still.
Oh and of course after wanting FF X-2 music to show up, they put it on iOS. If they put up both of Yuna's song and the battle music I'm gonna freaking RAGE!!!!
As for the whole CAN this come to the 3DS version. YES! Everything that is being added can and SHOULD come to the 3DS. A new mode and characters are not difficult at all. No need for a new cartridge. They'd just be saved and read off of your SD card. Just like the additional songs.
AUGH, all of this, especially the X-2 piece! I wanted that so badly on the 3DS and I'm so upset that the iOS is getting it but the 3DS isn't. Same with OWA: AC version but not near to the same level. DX
At the most, they'd need to put an update in the 3DS shop in order to let us have the new mode, characters, and tracks. It's frustrating that the iOS gets all the nice things but those of us who can't afford an iPad/iPhone likely won't be seeing many things we wanted on the 3DS anytime soon if at all. >C
When KH3 releases, I will eat lots of popcorn watching people be lost as they don't understand anything that was in the handheld "filler" they skipped
