Did they notify consumers that they were bundling a warranty, sounds like all the purchasers should be due a partial refund and any people with damaged discs should get replacements, under their warranty.
There's no mention of a warranty on the Evil Within 2 support page

And no mention of a warranty on their main website either.
The amazon store page says that for warranty information, you can contact the seller (which would be amazon, and presumably amazon's warranty) or that more information may be available on the manufacturer's website (and the above links demonstrate that it isn't).
So yeah, my question is "Does anybody know about the warranty, and if not, how is a warranty that you don't know about materially different from not having one?"
