Probably as good as any delivery format that the people priced out of the C300 will use during this camera's lifetime.
I.e. Youtube and Vimeo etc. will do more damage than the camera for the foreseeable future. So will lesser projectors.
I know lots of ego's in film probably dream their film will be a sleeper hit pulled out of the dustbin and ushered into glory, and therefore want the best possible print for posterity. But I think the three or four cases that pull that off will have a certain swagger that their film was so good it survived the weak and cheap technology it was made with.
Therefore I'm not seeing a problem. The moire and aliasing on the 5D2 was a problem.
