I expect PSNeo will officially be called PlayStation 5. Then Sony will announce from this point onwards, every new iteration of PlayStation consoles will be fully backwards compatible with PS4 games onwards, newer games will work on older consoles until they're just too much for it to handle (similar to smartphones). PS5 will have a catchphrase similar to Scorpio's "Beyond Generations", thus ending the traditional console cycle as we know it.
We're getting crazier.
