No, remember I also said once we get the source code we can make a fork, divide all the RIpples evenly between all the people who claim to have thought of a more fair distribution method, and let them all apply their method to their share.
If OpenCoin waits until there are already a fair number of well established gateways that have regular transaction activity, it will be virtually impossible to convince these gateways to accept a fork. Especially if these gateways would lose their generous bribe of XRPs from the OpenCoin billionaires stash. It would have the same chances as one of the alt coins like Litecoin surpassing Bitcoin (i.e. impossible).
