imo, probably the only reason there's a PS3 and PS4 (and Vita) version for Minecraft is simply because the versions were released - or at least in major development - prior to Microsoft taking over.

At that point I guess they figured they could milk some extra money from non-xbox players by releasing/updating them.

Of course they probably wanted to desperately avoid "oh look at that. Microsoft's shafting the Sony console players of Minecraft." blame that would have definitely been leveled at them.

I just blame the guy that ran away the instant he got backlash for trying to put his foot down on the server abuse (servers bilking players for "ranks" and shit for ingame perks - some servers to the tune of 1000 dollars or more.)
