Fooflexible... It just isn't going to happen. Why would a massive company like Sony... Who can manufacture absolutely everything in-house... Who has driven 10 years of growth in the home console arena... Want to become part of a "consortium"?? Reduce their risk, sure, but also reduce their potential returns... Its also probably going to result in a worse product... How does a "consortium" do effective hardware/operating system integration as is now essential for every console? How do the companies even get a basic direction for the system? It just doesn't make much sense.
"[Our former customers] are unable to find software which they WANT to play."
"The way to solve this problem lies in how to communicate what kind of games [they CAN play]."
