It looks like Jett Rocket on WiiWare was a success. Now we're hearing that Jett Rocket is indeed returning, this time on the 3DS eShop.
We don't know the details behind the return of this character, but it sounds more like a new project rather than just a port. We can expect to hear more details later this October.
This looks great! This game was pretty good on WiiWare, I can't wait to see what Shin'en can make with the 3DS and Jett Rocket.
