UPDATE: They have the non-Design models up on Amazon now. There's only a Black and Space Blue version so far. I'm personally waiting for the Design model... I've been checking every day just like some of you have been so hopefully it comes up soon.
UPDATE 2: The Fusion X cases are now availabe on Ringke's store and the Design model is there too, but it's currently showing that it's sold out. They are likely still waiting on them... Hopefully just a bit longer.
UPDATE 3: The Design models are now available to purchase on Amazon, but they won't be in stock until next Monday, November 11th. Just click on any of the Amazon links above.
