We're not exactly how much impact this will have the next time a civilized conversation with a gaming buddy sinks into the depths of fanboy warfare, but here it goes: According to a recent survey conducted by Game Developer Research, as reported by IGN, there are more developers working on Xbox 360 projects than there are on the Playstation 3 or Wii. Specifically, 78% of those surveyed were working on 360 projects, 58% were working on PS3, and 42% were working on Wii. As the numbers imply (notice they don't add up to 100%), they include both cross-platform games and developers that happen to be working on more than one console. This also means that the 360 doesn't necessarily have the most games in development. Still, it has the most individual developers of any console.
Now just find some way to spin that into a catchy slogan and you've got some new fanboy ammunition (fanmunition?) to go with your new (toy) fanboy gun
