This will be tough for sony, if they do. First of all, Gaikai delivered a technique for x86 and not cell so development cost goes into there. To deliver a good gaming experience Sony has to deliver high-performance-servers all over the world, connected to very high-speed networks before even one customer pays 1 cent. And they don't know if there are enough customers to accept this solution as most probably many ppl will complain about the service as it is crucial how they are connected to the internet which Sony can't influence but the customers will still blame them.
To me it is too risky, too early and could end up bad for Sony.
