According to Wii Everyday, this suspiciously tiny snippet of a page from Shonen Jump was posted on 2ch. It very clearly features the original Chrono Trigger logo and a note that it's coming in 2008 from Square Enix. We'd be more likely to believe that this is a joke from some jerk 2cher than real evidence that the Square supergroup's RPG is being remade for a DS release this year.
That is, we'd be more likely to believe it was a joke if not for this. Seriously, click that link. You will say "wow." Now all we need to know is if this is a port, a remake, a sequel, or a card-based spinoff!
