Might not be Toriyama, it could be the marketing department and/or the higher ups who did that.
Remember that lots of Japanese companies are trying to cash in on WRPGs and their "Medieval European Fantasy" setting. That's the only reason Capcom made Dragon's Dogma, they saw The Witcher 2 and Dragon Age II and tried to copy them.
Given how little the Japanese QA test, combined with the short dev cycle, it will have lots of the game breaking kind...or the gameplay will not be anything like what they're talking about. I bet the latter
