There will always be gates of some kind people need to deal with that , yes they said they not going to lock stuff behind the MSQ for 4.0 but that doesn't mean all gates are removed. If they do raise level cap to say 70 I'm sure there be content out there that will require you to be 70 to do it or least a certain ilvl. Just depends on how big those gates are but there will always be gated content in some way.
