This is already planned and either explicitly announced or heavily foreshadowed in the game:Quote:

3) Final example: Admiral Theramore's attempt to destroy Durotar failed in The Frozen Throne, but his fleet was not totally destroyed. Newbie orcs and trolls who invade his citadel and kill his lieutenant can find papers in a locked chest that they need to bring to Thrall. The papers detail how a portion of his fleet went to circle Kalimdor and map out safe harbors and such, and that, should Theramore and his lieutenant fail, when they came back around to Durotar, they were under orders to bombard Orgrimmar and destroy the orcs once and for all. The fleet is out there, and circling back around towards Durotar ... it's a safe bet there will be a human invasion of orc lands at some point after the game goes live.
