Jump Festa just opened its doors at the Makuhari Messe a few minutes ago. Square Enix didn't wait long for the surprises, as it updated its event lineup page with two new titles.

Joining the previously announced list are Final Fantasy IV Complete Collection for PSP and Chrono Trigger for cell phones. FFIV is playable in the Square Enix booth. Chrono Trigger will see its first trailer.

Both games are due for release in the Spring. Square Enix did not list a carrier for Chrono Trigger, must most Square Enix mobile titles hit iMode first.

We've dispatched Alex to Makuhari for our Jump Festa coverage, so be sure and check our Jump Festa event page throughout the day for live reports.
