If this news is true then Mohan must have decided to hide the MR marriage truth from Megha. (Its doubtful that he told her on the wedding day morning and she understood and forgave him and decided to go ahead with the shaadi in the evening - though I wouldn't mind that !!!).
So the reality of the situation is that CVs is giving us 2 options.
ONE - Mohan's character is saved but MM marriage gets indefinitely postponed and he could stand to lose Megha for ever.
TWO - Mohan's character is destroyed (they will somehow try to revive it later through some obscure logic) and he hides the MR truth from Megha and MM get married.
From the precap and the TT article it looks as if it might be option 2. It makes a majority of viewers happy as MM FINALLY GET MARRIED - aagey jab bomb phootega tab dekhi jayegi. Also it allows Cvs to weave new twists post MM marriage through Riddima.
