Did you say you wanted more Final Fantasy/Disney crossover goodness in high definition? Good, because here's the first trailer for Kingdom Hearts HD 2.5 ReMIX.

A post on the PlayStation Blog from Mat Kishimoto, Associate Product Manager at Square Enix, featured the brand new trailer as a holiday treat from the Square Enix team to fans everywhere.

This ReMIX is the continuation of the story from the 1.5 ReMIX and features Kingdom Hearts 2 Final Mix, Kingdom Hearts Birth by Sleep Final Mix and HD remastered cinematics from Kingdom Hearts Re:coded.

After playing through both ReMIXes, you might find yourself still a bit slightly confused, but at least you'll be (somewhat), up-to-speed on the major events of the series. You might even be halfway ready to play through Kingdom Hearts 3, whenever it decides to be released to the masses.

HD 2.5 ReMIX will be exclusive to the PlayStation 3 and can be pre-ordered here. There's no word on a hard release date yet, but you can probably expect it some time within the coming year.
