According to Deadline, they consider the renewal of AoS "to be on the bubble", which to me sounds like they are on the fence if it will happen or not.

"Agents of S.H.I.E.L.D. is on the bubble and could go either way. But it is the only chance for a Marvel series on ABC next fall as underwhelming freshman series Inhumans is considered dead. Despite its low live ratings, S.H.I.E.L.D. is a strong DVR gainer and an even stronger international seller for ABC Studios, as well as a marketing platform for Marvel, which should help its renewal prospects."

Keep in mind also that ABC also has plans for two additional live-action Marvel shows planned for their network. One being the John Ridley project, the other being the female-focused one. Though it still remains to be seen if those will ever get off the ground.
