Have they said if they'll be fixing the glitches like the item duplication one? I'd like to know if I'll have to carefully choose who gets what TM or not, or if I can just glitch the game and get them in massive amounts.
Nintendo said they are releasing them in all their former glory, soooooo... maybe. No way of knowing before it is released. Not sure what anyone else can answer.
Since they are adding features, though, I think it is safe to say no.
