It may not be written in stone but it may be written in a legal document. The problem is that contract which is still being kept close to Nokias chest. This contract, I have always suspected has an exclusive OS agreement. This means that even if Meego sells well, Nokia, Elop, the board, or even the stockholders can't do anything about it. This exclusive OS agreement is as plain as day to me, Elops talk about "beating android our number one priority" may even suggest it's a performance based agreement. No sensible CEO would put all their eggs in one basket without an incentive. No sensible CEO would say no to the fastest selling OS because "they want to be different", no sensible CEO would scrap a handset being released to the general public soon because "it's OS is not ready or progressing quick enough" in favour of a handset who's release is even further behind. You need incentives for actions like this, to me this "future disruption" is the end of the exclusivity contract, the ability to move to your own OS again as a safety net if the contract didn't work in their favour or renewal falls through.
