According to a recent tweet from Katsuhiro Harada, the designer of Pikmin is currently working on a new Nintendo IP. Why is the producer of Tekken relevant to this, you ask? Well, Katsuhiro and Masamichi Abe are former colleagues, you see.
What's that? Pics or we're lying? Well...
Nerr.
There's no solid information detailing exactly what the IP will be... yet, but of course, as we hear more, so will you.
