Today, I visited the PlayStation Vita Community Site and learned that Namco Bandai is making a 3DS version of Crayon Shin-chan, and it will be playable at the Tokyo Game Show.
Of course, this is just from the site's news feed, specifically from a Dengeki Online article. But Sony may want to check its filtering system.
I don't think you'll find any future updates on Crayon Shin-chan at the Vita community site, so check the game's official site.
