if Ghash hits 51% its not gonna be good guys.
The split will cause big chaos and probably negative effects will happen to bitcoin.
It already hit 51% once today. Doesn't seem like they were preparing for an attack. A modified client would need to be used in order to take advantage of having more than 50% of the hashpower against the network. It doesn't seem likely that a big company like them would want to do this to themselves. Atleast that's what some people've been saying.
