How much longer do you think that the manga is going to continue?

i think that hitman reborn will end at the Shimon arc. i mean since Tsuna was asked about being the boss of the Vongola Family,wasn't that the point of the whole anime.

i also think that revelation of the arcobaleno will not be revealed since it their secret was already revealed. i don't think that there's more coming about that.
Just my opinion hahaha

I don't think it will end at simon arc or raibow curse. I bet there's still a few arcs in the future
