lol Tabata wanted to be specific with the 50-60% progress and that is the progress he has made over the 2 years he became director and the 2 years they switched from ps3 to next-gen which means it'll probably be finished faster than you would expect.
Also, I hope the no playable female character changes when it gets done, even a bonus/secret character/minor character would be great. If not, then I hope they'll have a really strong female character in the game, villain or not that would have a large role in the story of FFXV.
