Preface: I'm posting this mainly for informational purposes, and not to take bets on whether anything will actually come of it. I also strongly support the New Neverwinter Vault, for reasons too numerous to name. But I also think it would be valuable for other reasons if IGN's Neverwinter Vault were to return, not the least of which would be the restoration of the comment and review history on so many modules and other works -- which is otherwise now lost forever.
That's one of the reasons why I've been "poking" IGN's management every few months on whether the IGN Vault -- which still showing an "undergoing maintenance" page -- will ever be restored. My plan was to continue doing so until they either said "No, it's not coming back," or "Yes, it's up now," and I saw a corresponding change in the landing page. On that point, here's a link to my last Twitter exchange with Talmidge Blevins:
Andarian: Any news on restoration of the Neverwinter Vault?
Talmidge Blevins: Now that 1Up has been restored, it's what the engineers are currently working on.
Unlike the previous responses, this one said that their engineers are actually now actively working on it.
Given that IGN's NWN Vault went down nearly a year ago, there's good reason to be skeptical. But if they have only a small engineering staff to dedicate to the effort, and if that staff has been busy cleaning up other messes from last year's (at least partly botched) migration effort, then it's possible that the old Vault might eventually come back online. As I said, I'm not taking bets, but I thought I should mention this news for the record.
