Where have Abbas- Mustan disappeared?

The best suspense movie director duos who made films like Baazigar, Khiladi, Ajnabee, Humraaz and so on are not to be seen around these days. I would really like to know what they are planning next. The kind of movies they made are remembered even today. They are the ones who gave Shah Rukh Khan and Akshay Kumar their first big hits. 

Have both of them also succumbed to the changing methods of content consumption in India? We get it, they have been in the industry long enough to take things easy but the Burmawalla brothers were the best we had in terms thrillers. Why don't they helm a web series at least?

They were the ones who made Akshaye Khanna play negative characters and win the heart of the audiences. I hope they plan something big in the future or make a good suspense web series which would be quite an interesting move keeping in mind the gaining popularity of OTT platform. Hope we hear something is cooking behind the scenes.
