There's more to sony's answer than that but they couldn't go into the details of why they wouldn't allow cross-play with that particular game.
Phil shouldn't be trying to make it seem like sony is the holding back cross-play when microsoft's track record show that it's been against it for a while. Will MS allow crossplay on FFXIV ARR with PS3, PS4 and actual pc? No. Otherwise they would have a copy of it on their consoles. Both SE and sony said they are up for it.
