1. Make Grid computing node engine, code name "cell" (If you read the original design intent, it was stackable to build supercomputers . . )
2. Convince Someone else to contribute to R&D - re Sony, in the name of a powerful games engine. Preferably a company too arrogant to admit when they've been duped and have to go buy a graphics chip as well.
3. Laugh all the way to the bank as said company subsidizes your product into the market and convince said company to give your core market linux to use the Cell in their data centres, under the pretence of them getting an EU tax rebate.
