Just what I was going to comment on. Perhaps we should ask Gabe Newell to have a word? They collaborated on old Half Life expansion packs after all. 
This is an old thread…does anyone know if the ps4 version could include exclusive DLC?
If there is any exclusivity, they are likely to only be timed exclusives, meaning PS4 would be able to experience the DLC exclusively for a set amount of time, prior to its release on other platforms. PS4 seems to have had a lot of timed exclusives across a number of titles this console generation. Off the top of my head, I am aware of timed exclusives for Destiny and Call of Duty DLC. If you’re interested, you can read more about timed exclusives here. For whatever reason, Sony has been absolutely killing it when it comes to snagging exclusivity over Microsoft. This may even be evident in the fact that PS4 gets access to the Battleborn Beta on the 8th befor XBox and PC on the 13th.
No exclusive dlc. They get to play Toby in the beta exclusively, but otherwise they will get the first dlc pack for free (if you play the beta on the ps4)
I never played the beta 
Yeah, I posted this because as you have said, ps4 always have timed exclusives, so I figured out if Battleborn may have a DLC
Beta starts April 8 for ps4 and April 13 for PC and Xbox so you have time 

thanks
not always, i sorely miss killer instinct.
