Interesting numbers. The problem is that if no one updates then we will have some problems. However Gavin said that he wanted to start early because if it is going to happen, it might take 6 months or longer to get switched over to the new version.
Miners are also going to play an important role into this. While Mike claimed to have spoken to several service providers, we know that he was into disagreement with Chinese miners not too long ago. It's surely going to be interesting watching this.
What Chinese miners arguing about so hard? This change is not something radical like making fork 20MB instantly. It is like they want to have block bitcoin evolution and keep progress at bay.
Change like that is the middleground and I think everybody should be happy about it. Only a fool would think that bitcoin won't be changed in the future.
