Hmm, didn't say it the way it meant that..

I mean, Sarutobi is dead, right... Konohamaru aint an important character anymore, so also his father ain't that important.
U could guess all u want, the anime doesn't say who Konohamaru's father is/was and with Sarutobi dead i don't think we will ever get to know it.

This topic is just like the "Who is Naruto's father", "The 4th is Naruto's father?" topics, things u can speculate soo much about but u can never figure out unless they think it's important enough to put in the manga at some point...
