@Ryuksgelus:
An info box telling us Buggy is a warlord would just be beating a dead horse. Only way he is not a Warlord is if he refused.
If by "beating a dead horse" you mean "official confirmation of a something most of the fandom has come to accept as unofficial fact", then yes.
ps: That idiom doesn't mean what you think it does, BTW.
pss: Just to save people from typing paragraphs consisting of their reasons why Buggy will be a shichibukai, I'd just like to point out that Yes, it is most likely that Buggy is going to be one of the new warlords, but that's not the point of contention here. The point of contention is whether it has been confirmed in the manga or not, which it hasn't, and won't be until we hear news of Buggy again.
The strongest indicator is that he got was a bat from the world government that matches the one Jinbe got, which makes it really likely. But "confirmation" means a totally different thing from "strong indicators to support theory", and as I said, short of a headline with "shichibukai Buggy", or an Odabox or some mention of Buggy and his new position, it's still unconfirmed as of now.
