Jr NTR will be done with Devara's shoot by the first half of 2024. There is still a fair bit of shooting left but the chances are that the entirety of the shoot will be done by the second quarter of 2024. And once Devara is done, NTR is supposed to work with Prashanth Neel for his next film.

However, the thing with Prashanth Neel now is that he is looking to work on Salaar 2 before commencing any other projects. He is looking to cash in on the Salaar 2 hype by starting the sequel at the earliest. 

In case Neel goes ahead with Salaar 2, then NTR will be left with no shooting after he is done with Devara. This is where the speculations are rife that NTR could be working with Trivikram once he is done with Devara.

Trivikram too is left with no project in his hand once he is done with Guntur Kaaram. So, the chances are that he will readily accept NTR's proposal once the Nandamuri hero comes asking. 

The talk is that NTR has primarily floated the idea with Trivikram but a serious talk is yet to be had. And if the two of them decide to come together, then this will be NTR's immediate next film after Devara.
