He said the same thing to me about FF12 at E3. Actions, not words Kitase.
I doubt they'll announce it before they get X and X-2 out the door. And if we're talking about actions, the fans can step up and support X and X-2 on Vita if they want to see HD remakes continue on portable systems.
Money speaks a lot louder than words on a forum. If both games bomb on Vita, I don't know why anyone expects them to put out XII HD on it.
As for his observations about the term JRPG, it's pretty much spot on. I personally don't like the term and find that its only used in a derogatory sense, and is purposely manipulated to shit on Japanese games. You see people try and argue that Dragon's Dogma and Dark Souls are actually WRPGs, which is absurd. If it means RPG made in Japan, then yes, it also includes modern games that aren't anime style with 16 bit aesthetics. People try and segment these games out of the label because they want JRPG to be synonymous with outdated design, when that isn't the case. Both Dragon's Dogma and Dark Souls blow away anything Skyrim is doing.
However, I could live with people using the term JRPG if they also started using nation-based terms for all the other games, instead of grouping them all into "western." That's basically what he's saying. Put "JPRG" up against any other single nation, and it comes out pretty damn favorably in a competition. Put it up against the entire rest of the world and it's just unfair, and it becomes clear that people only use the term in a derogatory sense.
