Square has gone out of their way to shut down two fan-made projects revolving around Chrono Trigger, and for whatever reason they've yet to get the point that the Chrono series could be extremely profitable.
Even if CTDS sold poorly, there would be a legitimate reason for it. The game has been released twice already, and just look at their other games on the DS (i.e. The World Ends With You, Kingdom Hearts 358/2 Days, Final Fantasy IV). Look at how much effort was put into those games as opposed to CTDS, which was just another port of a 16-bit game with a few more extras. How many copies did they expect to sell?
I hope someone at Square watches the videos of Crimson Echoes on Youtube and realizes, "Holy crap, these guys were so dedicated to our series that they managed to tell a story better than most games we've made in the past ten years. Maybe we should make a game like this. King Zeal is the FUCKING SHIT."
