Cross gen would be so cool. I think most ppl that have a ps4 upgraded from a ps3. When I got my white ps4, I didn't even know or care about destiny. Once I got hooked, I thought I'd get it on ps3 for 2 player, but sadly no. I'm sure it's the same for the Xbox generations. Cross platform would be interesting, but cross gen should be a must. From a sales perspective, no cross gen limits bungie's profits. I think it might be more a console manufacturer stipulation. Whatever it is, I sure as hell am not buying another console just for 2 player capability. I'll just let friends or family take turns playing with strangers.
