I'm just fine with a Chrono Trigger port, though I'd expect some new content ala the Final Fantasy Advance titles. However, I really hope this doesn't have the 3D graphic style from the new DS FFs. That's great for RPGs that really weren't that interesting graphically, but Chrono Trigger's art is still gorgeous and couldn't be captured in that engine as it stands. Luckily, I don't think that's the case, as Matrix Software has been busy doing FF IV. Would love to see them do either VI or VII next though.
I was utterly disappointed when Chrono Trigger Resurrection was canceled (which actually did translate the art into 3D well), but it seems like Square Enix had a reason. Huzzah.
