Honestly at this point I don't see how there could be any debate that Danzou isn't Mandara and it kind of makes sense in that he'd be playing both sides. Just like how Palpatine had the entire separatist fleet run to Coursesant just to kidnap himself to secure his innocence Mandara sends pein to konoah so he can finally take power which makes getting naruto a lot easier since he can keep him in the village and limit his travel.

If you need any other proof take a look at these two manga pages.

They both have the same hair style. If that's not enough proof in manga terms I don't know what is.
The only thing these pages show is that both Danzou and Madara are old (so nothing new really)... and that they both have a sharingan in their right eye. BUT Danzou's sharingan has got those "strain" lines in his eye, which might suggest that his eye is NOT his natural eye and is a transplant. I can't remember wether we ever saw this with Kakashi or any other sharingan user UNLESS mangekyou sharingan was used and with Danzou it's just... sharingan :P

Imo Kishi is fooling us into thinking Danzou is Madara, but I might be dead wrong of course

as for hair style - maybe they visit the same barber

EDIT: to above - you did not think Kabuto would betray Oro? Even Oro suspected Kabuto of betrayal like at least twice... First time was in chuunin arc I think, when Oro said sth like "If you want to stop me, you should do it now Kabuto" and the other time was encounter with Tsunade.
