Right now, it's unclear what the hold up is on cross-platform play between the Xbox One and PlayStation 4, other than that it's a business decision by Sony.
Unfortunately though, it appears that cross-play won't happen between PlayStation 4 and Xbox One players. However, despite all the solutions that the company is offering, there's still one that hasn't been made - PlayStation 4 owners won't be able to play with Xbox One owners.
In what could be seen as a subtle dig at Sony, the post also states "Contrary to what may have been implied, Microsoft has always been a leading voice in supporting cross-platform play, connecting players across PC, mobile and all consoles". While a second announcement detailed cross-platform play between the Xbox, Mobile, and PC.
However, Sony is still not "willing" to feature cross-play with other platforms as they want to safeguard their players' information and the children from "external influences" and that's according to Sony Interactive Entertainment's Jim Ryan.
PlayStation 4 players can play with PC, Mac, and mobile.
Now we've received confirmation that Xbox One will in fact support cross-play, cross-progression, and cross-purchase, between Xbox One, PC, Mac, iOS and (in the next few months) Android.
Last week, Epic Games announced that the hit base-building battle royale title will be making its way to mobile devices.
