Relationship between Hope and Lightning will "develop" in Lightning Returns?

Hey guys, I came across this video. Whilst I do not want to get my own hopes up, after watching 5:05~ in the video, I am assuming that there should be SOME kind of development in the game between Hope and Lightning. I mean look at those girls in the video, they sound and look just like us (the fangirls who are shipping them lol)
