If people are speculating it is Jirya then they are pretty much not thinking straight. One. His body is under the seal, the pressure there, as stated by Kabuto, is dangerously high, so an edo tensei would be impossible, because the jutsu gives hints of it, the eyes and skin. If it is Jiraya, why would he have a change of view? Why would he decide to turn evil after a student of his changed the world like he wanted? I think these theory and speculations are from those who want to see Jiraya return and fight Naruto.

I doubt it is Jiraya, it is most likely just another Toad summoner who takes up the red tear mark. Like that Kid who was a Killer B fan. Or Gaara son who everyone thought had Shukaku in him.
