If you want to get the premium version the Kingdom Hearts II HD update for PS3, it's going to cost you $100. Pre-orders are open now for Kingdom Hearts 2.5 HD Remix, which is only available online through the official Square Enix Store.

Here's what comes in the collector's edition:

Disney collectible pin that features Sora and Mickey Mouse back to back, with a keyblade dangler. Made out of a soft enamel coating on metal, this pin’s height stretches out to 1.68 inches.

Square Enix is also offering a Limited Edition option (which is the only other version available if you're pre-ordering). For $40 you get three games: Kingdom Hearts II Final Mix, Birth by Sleep Final Mix, and Re:coded as well as the special edition Disney pin from the Collector's edition.

What do you think? Are you going to pick up either version to brush up on the convoluted lore of Kingdom Hearts before Kingdom Hearts III comes out?
