Why was there no plot development for a confrontation between Neri, Michael and Tom in part III!?

That alone would have been enough for a film. At the end of 2, Neri clearly has Michael's ear and is pushing to be his #1 ace. Seems he succeeds, to be honest.

If anything, part III could have been great with Vincent, Tom and Neri trying to gain control again of the family again.

"That's right. That's where I want it met."
