I'm aware of the Cell's requirement for highly optimized code and that this requirement which seperates it from the other systems. That's why I listed it with the unique features of each system. I'm not quite sure what the disagreement is over since I agree that games optimized for the Cell will be impossible to translate directly to other systems (just like live or wiimote optimization). I don't think it would be impossible to move such games from the PS3 but it would require the dev to redo the game engine from the ground up (as in not even try to use any aspect of the PS3 code) and would produce a game with lower graphics, less AI, fewer characters, etc. If the money is there to do it though 3rd party devs would be stupid not to.
It will be interesting to see how this affects 3rd party devs though. If it turns out that making blockbuster expensive games for the PS3 isn't worth it (too early to say at the moment), will the they choose to optimize for the PS3 then pay another $3-5 million to make a new game on the Wii or will they make make the game as simple as possible on the PS3 to cut costs and cover the Wii port. Having a unique system has its advantages if you have a system that sells well. If you don't it certainly makes things interesting for the 3rd party coompanies.
