Whatever, because Nikon D3X is better than 1DsMK3, Canon must retaliate. So yes, Canon will come up with something very, very soon. Not sure of the name though.
Nikon will then hit back, not to come up with some better than 1DsMK3's replacement but probably a scaled-down version of a 24MP FF that will beat the 5DMK2.
So what's your point? Do you really expect Canon or Nikon to stop releasing new bodies or to stop competing? Every manufacturer in every industry competes with every other by continually releasing new models, whether it be computers, cars, TV's, toothbrushes, or any other product you can think of.
