Sony, mostly because they aren't really bringing anything to the table anymore. Imitation != Innovation. Anyone who fails to contribute to the game industry's evolution is just hampering it.
MS brought us Live, a great online service for remote multiplayer gaming, along with HD graphics. Plus they are changing the way motion controls work, sans controler.
Nintendo brought us modern motion control gaming, opening a wide spectrum of gaming possibilities (which yes, also include casual titles and Imagine Babiez lol)
Sony just said "Lets take HD graphics, and we'll also take that notion of motion control Nintendo came up with, and work around the patent"
Sony has contributed the least in the past 5 years to the industry, so if one had to go, it'd be the dead weight.
