I still hope Singham 3 happens but I heard some rumours on the net that Salman Khan or Hrithik Roshan will have a cameo in Sooryavanshi. That cameo will be like Akshay in Simmba where it will lead to a solo cop film. On paper, this may sound good but it will be logical for Rohit Shetty to direct Singham 3. Why keep waisting Ajay Devgn in too many cameo appearances? He's already had two and Shetty could giving a sequel in return for Ajay. With Akshay & Ranveer, it's already building up towards multistarrer film in future and I don't know how other characters will fit in this cop universe like Salman.
Honestly, Singham 3 deserves a sequel after Golmaal 5 and it will create an impact at the Box Office if made today. It's the best way to take Baijrao Singham's character forward and show his backstory that occurred during the events post-Sooryavanshi. Then Akshay & Ranveer can have cameo appearances.
