Just came across a Rage 2 Steelbook Edition listed on Amazon. Appears to be Amazon exclusive:

There's a separate steelbook available in the collectors edition, but I prefer Amazon's. Wasn't planning to pick this up on day one as I still have a big backlog so I'm hoping it will still be available when it goes down in price. Also hoping the same will happen with Amazon's Days Gone Steelbook Edition.
