This is what the Amazon 1st party listing says about the Arkham Knight bundle.
"Back-ordered. Due in stock September 5 -- order now to reserve yours"
So it's all 3rd party only sales for this bundle until September.
The Taken King Bundle looks like it has run its course on Amazon with no prospect of any new shipments becoming available to Amazon. Is it still available at other retailers or is it all gone from eveywhere?
