Announced earlier today via Famitsu and being demoed in Japan as I type this (literally), a new Crystal Chronicles title with quite the twist: It can be played on Wii & DS...at the same time!

Final Fantasy Crystal Chronicles: Echoes of Time will release January 29th, 2009 in Japan, but the most interesting part of the game is it's dual system functionality. Feature list, scan and debut trailer below:

Features + Pollux Engine, developed by SquareEnix, allows simultaneous play on Wii & DS + Wii and DS players can play together online. + Stylus Play for DS, Wiimote Play for Wii + Main Character named Charlotta, story revolves around crystals + Transfer your Mii's and use them on your DS

Should go nicely with your brand new Nintendo DSi, right?
