The patent process needs to be changed. You shouldn't be allowed to come up with an idea, draw some stupid pictures that have no connection to how the process works, and then claim a patent.I say make "idea" patents only protect that very specific idea. So, if Nintendo came out with a product similar to this and used a Mii instead of an Avatar then they can legally produce that product since it is different.If Sony wanted to protect the patent from similar ideas like the Nintendo example then they would have to submit a mechanical drawing. It could be as simple as saying coaxial cable goes into box. The box processes and places Avatars in image. Coaxial cable goes from box to display on screen. After they submit that mechanical patent they then have a set amount of time to come up with a working prototype with a possibility of extension if they show progress. Taking the prototype route should be the only way to insure similar products are not made. If Sony came up with a prototype then someone could not come up with a product that uses composite cables instead of coaxial. However, if they only submitted the "idea" patent or failed to produce a prototype then they lose rights to protect against similar products.
