I don't understand how it is general knowledge Disney doesn't know the name. We don't know the name and anything they file will not have the new name as they don't want it leaked yet. But none of this means they don't know they name. Sure, they may not know. Maybe they have a small list and haven't picked one out yet. Maybe they are trying to figure out phase 3 and then come up with a name. There are many scenarios, but honestly I am not sure why it is a big deal. They have 2 years before they need the new name. I am not sure why this is even a slight against Disney.
And trust me, I make fun of them for a lot of things like how slow they are, how they haven't done poop in a long time, how Pandora doesn't belong in DAK or any park really, etc. But I am not sure how not having a name for something that won't change names for 2 to 3 years is at all a big deal.
