Masamichi Abe, the former designer of both Pikmin and Metroid Prime: Hunters, is apparently working on a brand-new IP for Nintendo. In case you didn't know, he also worked at Namco on Tekken 2.
In fact, it was the Tekken series director, Katsuhiro Harada, who shared the news on Twitter, responding to a question about Abe's current situation in the industry.
