I would imagine that it all depends on how profitable Kotaku is as a publication. If both IGN and Kotaku are doing well then there is nothing to be gained by merging them or destroying one of them. A lot of parent corporation run competing businesses under the same umbrella.
Of course, if one is lagging substantially behind the other then, yeah, could be lights out. I doubt all Gawker properties will make the cut. Only one I care about is Lifehacker.
Gawker.com, though, can rot in hell.
