It isn't quite that simple. Realize that Sony owns a gagillion patents for sensor technology. Canon isn't just trying to milk their technology for all its worth...although in doing so they are certainly in a better financial position than Sony (who is barely better than junk bond status for their latest debt purchase). Canon has to find ways to do things similar to what Sony's done with Exmor...without violating Sony patents. Canon knows full well their technology is old, aged, and smelling pretty stinky by now.
you realize that canon is in the top 5 for filing patents for years?

and if if canon would desperately need a patent.. they could license it or exchange patents with sony.
my company does it all the time, sony does it, canon does it.
patents are not the real problem i think.
but to have more circuits, more logic, on a sensor you need a smaller litho process.
and that is canons problem right now.
i predict that in a few years we will see a jump in canons image quality and todays cameras will have the stigma of "that last 500nm generation".
unfortunately that does not help me right now.
i don´t need better high iso performance, i need better DR and better detail rendering.
i do most stuff on a tripod at ISO 100 or with strobes.
for my sports photography (motorbikes) i could need the better AF of the 5D MK3 but it´s not really worth the money for me. i would not use it often enough so i could justify spending the money.
so i keep my 5D MK2 until canon produces a camera that offers a noticeable better image quality.
