have posted a Q&A with someone at Ubi Soft, lets call him Mr Smith, about Harpoon4, the extremely delayed naval-warfare simulation:

    There was some talk from Ultimation staffers that Harpoon4 had already entered testing. What work does the new team have left to do in completing the game besides testing?

    As you can understand, Harpoon4 is incredibly complex under the hood. There is a great deal of optimization taking place to make the simulation run smoothly. Any changes at this point require the input of testers to make sure that no additional problems are introduced.
