With past Pokemon games, people could have accessed all of the files in the previous generations. To my knowledge, there is no way to do this for a 3DS game yet.
So, how long do you think it will take to find out everything in this game? There seems to be a lot of areas that seem to serve no purpose now and we'll have to wait for the event Pokemon (if any). --- 3DS Friend Code: [2449-4631-5617 / Valm]
Outside of any potential event pokemon shenanigans, I'd say...as soon as the strategy guide is released. --- 3DS Friend Code: 0344-9443-2457, Newtown Dream Address (AC:NL): 5400-2162-1014 "Do you have the courage to ride with the devil?"
