[quote name='GBAstar']This is the first I"ve heard of this...
Is this just a gamestop exclusive edition that contains DLC or something? I'm assuming it is similar to what they dead with Dead Island when they offered their own GS exclusive Special Edition?[/QUOTE]
Yeah, they did it with Red Dead and Dragon Age II as well. And yes, it's a Gamestop exclusive I'm afraid. Try pre-ordering in store and ask. I was able to do this on Tuesday and was told I'd be getting the signature edition.
If you can, go for the PS3 version, first edition copies come with AC1 on the disc. Given the rarity of DA2 Signature Edition when it launched, it can be assured Revelations Signature edition will probably go for $90+ as well.
