I would put Malvika in the same category as Unnati and Tasnim. She does seem to have potential. We need to be a bit lenient with this batch as they have missed out on 2 years due to COVID and hence, there development will be slower compared to others. Considering that, I still have high hopes from these 3. Even Samiya and Aakrishi are not that old and can improve a lot. One more name to watch out is Anupama Upadhyay.
In MS, Meiraba is still young and has performed decent in his debut year on senior circuit. So, I still have hopes from him. Though I don't have high hopes from Kiran, but I think it is early to discount him. He is just 21 and already has some decent wins on senior tour. He can be next gen Prannoy. Among the rest, I think Priyanshu is another one who can be a top player. Also, for Paris, I have really high hopes on Lakshya Sen. And Srikanth still should be among top for 3-4 years more.
For Doubles, we have 3 very good doubles players in Tanisha Crasto, Treesa Jolly and Gayatri Gopichand. On men's side we have a number of good young players (Krishna, Vishnu, Ishaan, Sai) Plus we have the beasts Satwik and Chirag. So, there is hope that among such a talented pool (and with return of Tan Kim Her), we should get some decent doubles team as well.
