tell me one good reason why they wouldn't release it bare bone. it makes no sense to hand people DLCs they would otherwise sell millions of for $15 a pop. to be nice since the game came out on another platform earlier? you're making them out to be more generous than they are. if it's not a 'complete edition' released waaaay later (which is won't be) i don't see it. there's no incentive.
if you're already desperate enough to pay $120 for both versions you will pump money for the DLC. and if you're a newcomer, you're an easy sell. doesn't make any business sense unless it was a complete edition.
I wanted to say GTA IV re-release w/ episodes for PS3 as an example, but that happened after the release of the episodes... and way later anyway...
But usually late ports often had some of the DLC or other stuff included. Though that was mostly due to regulations like Sony has in place (if a 360 version came out first, the late port has to add
something).
I guess there's not much we can base it on, cross-gen-ports of big games is kinda a new thing. The better graphics alone could be seen as the incentive to buy it.
Unless it will take a lot longer and they really do a complete edition in 2 years or so...
Episodes as DLC for PS360, Re-release of GTA5+Episodes on disc for PS4/XB1. But you're probably right, they wouldn't wait for that.
