Ubi, I hate to break it to you, but using Sony as an example is an especially bad idea.
They don't have a great track record as far as innovations go. Anyone here remember Beta? Why did that fail? Oh yeah, they restricted the releases on the format to mostly (if not all, I forget) Sony-involved films. Many years later, the PSP came out with its UMD drive. And why did UMD fail? Oh yeah, nothing but Sony pictures (that changed later I think, but WAY after it flopped). Not to mention the numerous 'intentions' for their systems that never quite come to fruition.
Any horse they bet on for new consumer-grade tech, you can bet will fail. They should stick with what they've been good at: Improving stuff that already exists.
