Masteria Expansions, Names and the proof for each

MY question was about Ellin and time travel to Old Sappe >_>

At first I thought the question was:
(Translated)-Will we get Neo Toyko/Ellin Forest
-Yes

But, you don't take a ship to Neo Tokyo, do you? Ellin Forest is a machine, isn't it? In the Time Control Room?

Do you think we may go back in time for Masteria? It would hold a whole new dimension to Masteria; although I would be stumped on how they would fit the levels into it, considering we're already in the 100's with CWK.
