Regarding the whole current to next-gen copy for $10

Not sure if anyone will know the answer to this yet but, will the codes expire?

I guarantee it. I have no sources.

It's apparent on PSN. Sometime in 2014 the deal expires.

I actually have a question too. The playstation video I watched said that current gen games that qualified came with a code that tied them to your psn account and it allowed the $10 upgrade. From what I've seen they come with no such code.

Pretty confused.

Found it. So if anyone here has a similar question just look to this.
