But what about this.
Bitcoin is only worth something because people say it is.
What happens when all the GPU miners (70%+ of miners) move to scrypt and say Bitcoin is worth nothing?
Then what will the asic guys do? Trade among themself? Polish there shiny useless hardware? Cry over it and short it out?
In the end they could be left holding the bag and I think that would be great

This depends on the general public's perception on things as they are responsible for much of Bitcoin's jump in value. The Cyprus haircut was a big part of that.
Will they continue to invest in BTC when the true scope of the pre-order centralize Bitcoin scam becomes more public ?
The coins and the hashpower have been hoarded. The Crypto movement has been damaged beyond repair.
