Has Toyota any plans to introduce diesel variants of Rush SUV & Avanza MPV in near future?

Toyota recently has no plans for modifying any of their car on the international lineup as they are getting good numbers on petrol engines worldwide. Considering the Indian scenario, the addition of Toyota's newly developed 2.4L diesel motor or the much smaller 1.4L diesel is a must for selling both the vehicles in India. The major concern of Toyota India is the launch of new generation Fortuner and Innova, which would make their way to India very soon. Fortuner has been revealed in Indonesia whereas the Innova needs a bit more time for its overall completion. These cars are the best selling of their respective segments and Toyota's focus on their updated versions was a good step towards creating new sales records.
