To be honest I would like to go by end theory though dil se I am not willing to accept
By considering the situation
Those who got reply are the strongest fans of raabta who stood with it through thick and thin
Not some random spammers
So producers knows well the effect of playing with their emotions
So a lie or a joke that possibility is very low
About actors
I believe this decision was a sudden out of the blue one by zee tv
As even producers were postive and wanted a revamp during 700 epi celebration
Also for one month short span if they knew in advance I believe they wouldn't have gone for a shadi black money track rather winded up the existing ones with some preg track and end drama
So u believe that now they had to wrap up so quickly isliye actors and set doesn't have an exact answer when the shooting would stop
This is why I feel they say they don't know when exactly would the shoot end
Even today and yesterday goda track ki continuation hi shoot ho rahi he
Only other option is that
We may have a few episodes syada in ott platform if it is impossible for them to end the story properly due to sudden end
Like some epis will run only in zee5
And the next option is they are immediately starting a season 2 as per the channels direction isliye no announcement or end news or ye sab confusion
Last two seems to be the only logical options
But yes miracles can happen too
