Seeing Samriddhi happiness I think we can't talk about generation leap but since they got the news only yesterday it depends what will ph and writers decide now.
Imo they have two options: to do what they started and end story like it was planned and then start completely new story on new slot.
Or they can made changes in climax and that's how continue the show.they can kill of Sukor which will be definite death of Udaan, trps didn't increase coz of Anjor and new time is risky also.
Am in for first option if it includes Sukor, coz it means revamp of the show and who knows maybe bigger possibility for attracting new viewers.
Now we are left with makers and production, everything depends on their motivation and plans, which will depend on time slot Udaan is given.
If this is true, and since we have two confirmations from cast most probably it is, we may get new promo during the weekend or by start of new week with new timing. TA was suposed to air last episode on 12th Oct and if it's true and there were no changes then Udaan won't get that slot. Before shifting TA this slot was reserved for repeat telecast so I dont think they will be in hurry or need to fill it. Maybe they will pull off one more show. I have some feeling it could be IMMJ coz it doesn't have new story and show was said it will run for a year which it did. I think yesterday they celebrated one year. The only problem im this idea is probably Colors biased nature.
