Despite how people feel about Platinum doing NG4, still want to mention that Yasuda (Team NINJA) is spear heading the project. So if you see something that doesn't feel "NG", it's either a placebo or... might actually feel too Platinum (like big arenas), but he probably gave the OK anyway so it's his game.
Even if the game does well/doesn't do well, a TEAM NINJA guy looked over it.
