Since Jumping is confirmed, can we fall off a cliff, take damage, etc?

[Hycinthus]

One major difference between FFXIV world and other MMO worlds is jump and falling off ledges. In other MMOs, you basically can jump and fall anywhere, into the water, off a cliff, everything is open.

So in FFXIV, has this been confirmed: would all the invisible walls be taken out, therefore, we can jump off a cliff of La Noscea , into the sea? Everytime I'm fishing, I get this urge to just jump, and this has always been my dream.

Thanks for anyone with information.
