So you know how they are going to redesign Eorzea and most likely use the umbral era as an explanation?

I think it would be awesome if they did something a little like Rift and make the first few levels a tutorial in a completely different newbie area, which would be the old Eorzea and then at the end once completing something(fight?) they could be sent to the new Eorzea which is under the 7th Umbral era. It can work and would make sense if they tie it together with the echo, like the echo sent you to the past to witness the coming of the 7th umbral era. That way we can get the new redesigned Eorzea but still have the old one.
