Expecting that Chrono Trigger sequel anytime soon? It’s not called Chrono Bind anyways.
Square Enix’s registered a trademark with the name in Japan for domains chronobind.com and chronobind.net, suggesting a sequel could have been in the works.
Instead, as pointed out by Siliconera, it’s the name of a card game that is part of a DLC pack for Final Fantasy XIII-2.
This could be tied in with the upcoming DLC featuring Sazh. Just guessing. For the rest of Chrono nation, keep dreaming.
