same issue here but with a ps4 mate... this is what playstation said to me as i emailed them about this.... Thanks for your e-mail and confirming your account information. The simple reason for this is that the way PlayStation 4 processes software and applications is influenced by the hardware itself. Because PS4 is so different from PlayStation 3, running software is handled very differently, meaning that it’s just not possible to run PlayStation 3 format software natively. Therefore the publisher of the game must re code the game to work with the PlayStation 4. Most publishers do not offer a cross buy service for games or DLC but Activision have offered a free upgrade for the first and second expansion of Destiny but have not offered this on 'The Taken King' this is a publisher decision and cannot be changed by PlayStation. If you wish to discuss this further I would recommend contacting the publisher regarding there promotion. Drop us a line if you ever need us again. Thanks, Marc PlayStation Support So no more destiny for me for a bit
