This most likely means that players who have not yet done the Golden Lotus series never will. This I find to be a shame! I recently rejoined WoW and have been eager to see the Pandaria content, however there was never any rush (or so I thought). So this means that I (and a lot of players like me) might never get to experience the pristine Vale and its story.
I understand that Blizzard needs to move the story onward, and I support the world changing as we interact with it - but I don't agree with the removal of story content. Imagine new players opening the gates to see the corrupted vale? That doesn't seem very lore-appropriate.
So perhaps let the vale phase with your quest progression? Have it be ugly and corrupted once you finish the related quests and story first - think Theramore. Or perhaps, like Theramore again, give us a Bronze Dragon so we can switch phases into the past until we complete the story - much like Theramore, and to my knowledge, the Pandaria Starter Zone.
There was another thread like this, so I'll link it here: http://eu.battle.net/wow/en/forum/topic/7646865395?page=1
Hopefully we'll find a way to work with some phasing. It would be a terrible shame if a lot of new players never get to experience the pristine Vale and the associated lore.
