That, my dear friends, is what we in the business like to call "Hope for the Future." In what was looking like it would be a huge slump for the DS, with all the Zeldas and Star Foxes and Advance Wars done and gone, it was looking like the DS was going to end up in a Yankees-like rebuilding year with everyone involved denying this was the case. But Square-Enix has dropped a proverbial bombshell on us with what appears to be a teaser site for a DS installment. Clearly, there isn't any sort of information regarding…anything. No screens, movies, info…or even actually saying that it is, indeed, Chrono Trigger (though the clock and the "CTDS" at the end of the URL suggest it). Expect some info to come up during E3. In the meantime, check out MyGamer for more updates as they come available.
UPDATE: Chrono Trigger has been confirmed for the DS. The game will be an enhanced port, like the GBA Final Fantasies, rather than a full-blown remake, like the upcoming Final Fantasy IV on the DS, and will feature some other touch screen bells and a whistle in the form of a new dungeon. No release date or development information is known at this time.
