Season pass has always been $50 and gives you a $10 discount on the 4 map packs since they cost $60 in total.
The hardened edition for MW3 was a special limited edition of the game that cost $100 and included the season pass. So if you managed to get your hands on the MW3 hardened edition, you essentially got the season pass for $40 as a special deal.
They didn't do the same deal for the hardened edition for any other COD. It was only a MW3 thing. I don't know if they'll repeat it with Ghosts or not.
