Being that Darksiders II is by default the “Limited Edition”, it was likely that the collector’s edition would be a truly limited set to appease fans. Although still three months from release, the Collector’s Edition has already sold out at many major retailers.
A search on Amazon reveals that it’s out of stock, while Gamestop.com has removed the listing altogether. Some have reported that GameStop stores are cut off after 5 Pre-orders (three 360, two PS3).
The only major retailers to still have pre-orders open seem to be Best Buy and Wal-Mart. If you’re interested and haven’t preordered yet, head over there fast as we all know how sketchy retailers not named “Gamestop” or “Amazon” can be about collector’s editions.
