Climbing & Swimming

[Alukah]

Actually...on the beta forums they made a HUGE list of all the changes and things they are making. One of them was swimming. It was under the "Coming, but as for when, we dunno" section of it.

Yeah IIRC for the first expansion they had to pick between sea themed or sky themed and decided to go with sky. Underwater combat is indeed hard to implement on an already ongoing MMO, but that's what expansions are for.
