I WILL NOT accept or believe that Barun is leaving in Dec. because, why would he be leaving, when he has no other job line up. Yes his movie is coming out, but he doesn't know the outcome yet. Plus his is not the only lead in that movie... and if he has another movie offer, again, he doesn't know the outcome. I don't want to say the word, because I don't want to jinx his work or future, but you know what I'm trying to say LOL. Another thing, Barun got famous and fame from IPKKND, and the majority of his fans are from the show, why would he ditch his fans and suicide his career when he still uncertain of what the future will be?
The show wouldn't dare to replace ASR with another actor, because the fans are there only for Barun, because he is the ONE and ONLY ASR to everyone, and not one else will ever replace him, not now and not ever, PERIOD!
Now come to the rumors, if the rumors is that the show will end in Dec then I will believe 85% because I have no hope on them closing all the loopholes and the logical senses of the show. But it will end, because TRP is low and there is no more story to the show as what the track is showing now, beside exposing Shyam. If they end the show soon, in the height of its popularity, they can still capitalizes on the International fans when they come out with the DVD (reason, shows/videos was pulling from almost all sites). If they will replace Barun with another actor, the TRP will be worsen and popularity will goes down and they will probably lose the International fans as well, and what will they capitalizes on? So there is no way the PH or the Star Plus will be that dumb to let this opportunity of making money go down the drag just like that.
So therefore, I wouldn't care much about the rumors, just ignore it and enjoy the show for Arshi moment together, while we still have the chance.
