First and foremost, I don't know the exact value of the company, but I know it's easily a multimillion to billion dollar company, and one less person buying their cameras- they won't miss that money, there are hundreds more out there who are interested in them.
I think this is not valid ...you must tell this to Nokia, Kodak, Philips TV etc. We will see Apple's destiny, history was always cyclic, now Apple is on the wave, tomorrow it will be like Nokia maybe, who knows. Any company (big like Canon or not so big like Nikon) must listen to any customer. And I really don't think in this moment (and after the first wave) there are people standing in line to buy 5D3.
I'm sure most of those who upgraded from the original 5D or from crop are really pleased. But those who upgraded from 5D2... I think they are not fully satisfied.
