Forget what happened with the absolutely dreadful Crash Bang Boom! game released on the Nintendo DS last year -- the new Crash design that Radical's working on for Sierra, Crash of the Titans, is also in the works for the dual-screen system as well, and scheduled to be released at the same time as the console versions.
Though Sierra didn't have the game on-hand when the company showed us the Wii version, it did give us an early look at the game through the modern miracle of screen grabs. In these shots, we can see that the company's working the action-based design with the same "attack and jack enemies" mechanics on the portable. It also appears that there will be some mini-game focus using the touch screen, including a pachinko challenge.
The Nintendo DS version's in the works at Amaze, known for the DS versions of Spyro as well as the upcoming Pirates of the Caribbean. The early views look promising, as the team appears to be incorporating a full-screen 3D engine for this version of Crash of the Titans.
