Masahiro Sakurai’s next project might not be related to video games:

“I have been away for awhile now, but I am working on something. My eyes may be a little tired. You may see me in the near future in a place that has nothing to do with game production. You may or may not be able to see me. I hope to see you again in the future. Thank you very much for your time.”

Sakurai is one of the hardest working game developers you’ll find, and he’s too much a student of video games to abandon game development forever. Even if he is taking a break from it, he’ll be back.
