Of all the things that the Cobra MkIV debacle can be blamed for, I don't see how it is blocking platform cross-play.I wonder does the Xbox and PC exclusivity of the Cobra IV have anything to do with Frontier's seeming reluctance to support crossplay?...
As many new Playstation Elite players might not even be aware that it was even available to unlock as a flyable ship, "back in the day".
Those that see NPCs on Playstation flying them, can dismiss it as a non player ship, but as soon as they'd see certain PC and Xbox players flying it, they'd flood Frontier's support pages asking, "Hey, why can't i get that?!"....
Frontier already have commanders on both PC and Xbox who cannot see / access Cobra MkIVs.
I suspect that it is one of those things that Frontier have de-prioritised because PC commanders are not clamouring for it.
