Isn't part of this whole cool story the tale of the brave defenders of the original one true bitcoin who will do just that? 
The cool story isn't when the miners bravely reject the large blocks, it's when the users of Bitcoin bravely reject large blocks, by doing nothing more than not installing any version of Bitcoin that removes the current 1MiB block limit.
Bravery by doing nothing; kinda anti-climatic really.
