A recent Q&A with the developers of Lightning Returns was really... depressing, on the whole, given the excellent legacy the Final Fantasy series has built up in the past, and the directions Square has recently (and continues to) take the series.
Among other ridiculous things they said, like how they're planning to out-open world Skyrim (really? with a timer?), apparently they also felt it was a pressing matter to let the public know that they're increasing Lightning's bust size to a D cup, and that she'll jiggle when she moves - just how much depending on how you equip her.
Here is an article with a translation of the relevant part of the interview - it's a little bit more editorial than I would have liked, but the only other article I have on it (the one which mentions the Skyrim claim) is at Sankaku Complex, which I will not link here because nearly all of their ads are for H-manga and JAV.
I don't oppose having jiggle physics in games - that is literally the only reason I bought Dead or Alive volleyball (probably the only reason anyone bought it) - and it's not like the series has never had any crude jokes (apparently Cecil's favorite magazines are the Ninja Sutra and the Lustful Lali-ho). Still, something about this doesn't sit right with me. I guess it's a combination of the fact that they're changing her - they've had plenty of characters who were busty to begin with, but apparently they feel Lightning needs a boob job; combined with the amount of thought they're actually putting into it - it doesn't take much effort to add text to an SNES game making a dirty magazine key item, but to add jiggle physics (that adjust to the outfit she's wearing!) will probably take at least one of their programmers a month of work to do.
Honestly, I'm struck speechless. The Final Fantasy series used to have more class than this. Yes, even Cloud crossdressing to get into Don Corneo's mansion was classier than this.
