Think you will find 80+% of blocks with fake nodes ?

Of course, 20MB fake nodes. What's your point?

My point is that fake nodes dont' win POW armrace. That's why bitcoin is secure.
Then it's back to all things equal, the more numerous consensus will win. Poll above has writing on the wall.
You need 80% of hashrate to win. Not nodes.
That's already taken into account. The Americans nodes supports Gavin.
The Chinese are pragmatic and will follow Gavin.
There can be no victory against the majority.
