We’ve already generated 14 blocks since 74638. The builds of 0.3.10 were uploaded about 2 and 3 hours ago. Of the nodes I’m connected to, more than half are already 0.3.10. I would say we probably already have more power than the bad chain.
I think it’d probably be a good idea still to come out with another version that rejects connections from older versions - otherwise the network might remain rather fragmented for a while. :/
We want to keep the older clients connected so that when the correct chain overtakes the incorrect chain, they will switch back to the correct chain. Although I don’t know the specifics of how far back in the chain the old chain will accept a branched chain.
