I checked just now. He took some time. May be went and checked with senior person as well. He explicitly told me that last addition of kids channel was on gsat 10 and all future addition will happen on gsat 10. Recently they have been giving template and right info. This again appeared copy paste template asnwer. So hope this is right. This case becomes stronger as mpeg2 addition was a surprize and ideally can not happen under any logic unless extra space is alloted.
