There is a small chance that what GF meant by 'we want to surprise you' is either that there will be two versions with two completely different storylines that stemmed from XY (I do think this is what will happen, so it'll be X2/Y2) OR they do a prequel and a sequel to XY for the version differences.
It just seems like a decent business strategy, Fire Emblem has done it with IF and people would have an incentive to buy both games.
