It is currently not possible for me to pre-order TTK Digital download for my ps4, but it is possible for ps3. My guess is that this is because I originally bought Destiny digital edition for ps3 and later got the free uprade to PS4. What happens if I preorder TTK Digital download for PS3? Will it work for PS4 as well? Btw: Look at the FAQ for the digital upgrade: Q: When I download the free PlayStation®4 expansion version(s), will I still be able to play it on PlayStation®3? A: Yes. Your Sony Entertainment Network Account (PSN ID) will retain licenses [i]for both consoles[/i]. I infer from this that I should either be able to buy TTK once to upgrade both ps3 and ps4, OR I should be allowed to buy TTK for PS4. Can somebody confirm this for me?
