We really need satoshi now because if he somehow shows up and tell us what he thinks we should do then we might actually agree on one thing and then doing it, I don't think anyone refuses him only if he could speak out somehow.
It is very unlikely that he/she/they appear now to say what the best procedure is, but there are many competent developers working on it, and from what I know, it seems that segwit is not the only thing proposed by them... There is also another solution called FlexTrans, but I'm not sure if this would be a better solution.
