Multiple Language Clients in one Package for 2.0?

I am a North American player, own the NA client of the physical game (CD), but have always played FF14 in Japanese.
Similarly, I am assuming that there are a number of players who may live in a certain region but instead choose to play the game in a language that differs from their own (e.g. a European player utilizing the English or Japanese version of the game.)

Will this "all-inclusive" feature of the game as it exists in its current state continue unchanged even after 2.0? I think it would be awesome if players continued to have access to all language-versions of the game client.

お願いします、吉Pよ！

Yes, please.

Especially if I can change at will (or even during game play).

I doubt this will change.
It should be cheaper for them to ship everything in one package anyway.
