@Kairouseki:
That counting to ten thing is pretty interesting. If he really was counting Vivi and Sunny then why doesn't he mention their names with the others?
Maybe because he didn't have a rendezvous point with Vivi, and he doesn't plan to meet she so soon, so he only mentioned the ones he can and wants to meet as soon as possible.
He may also have counted someone else, like Garp, Shanks, Makino or Dandan. Now that I think about it, he may have thought of a bunch of people, more than 10, but just there wasn't enough fingers in his hands.
But then again Oda already said that Luffy always says everything he thinks (reason why he never uses "thinking balloons" on Luffy)…
Anyway it isn't something so important right now. So maybe if Oda puts something else about it in the manga after a while, we come back to it and discuss about the implications, but right now there isn't much we can argue about it.
