In the past LDW have signed an agreement with BigFish Games that they should have sole distribution rights for the first few weeks. (At least, that's what happened with VV2 and PT.) Assuming they strike a similar deal for VV3, that means that other distributors like Incredigames are likely not to be able to sell it until about a month or so after the game is released.
