The Overwatch Reaper statue is finally up for pre-order! It is divided into two waves (two different ship dates). It costs $150, no idea how limited it is.

The Chinese knock-offs of this statue have been showing up on eBay for a couple months now. There are also a lot of PVC Genji statues, so I wonder if Genji will be the next statue...
