Frankly speaking, I can't understand the actual output of this merger.
I think, now Sony and Colors both are from same parent company. If this is true, then surely Sony will rebrand all Colors channel with Sony prefix, i.e. Sony Colors, Sony Rishtey, Sony Cineplex, Sony Infinity, even regional channels like Sony Bangla, Sony Kannada, Sony Gujarati, Sony Tamil etc also.
Then what will be the condition arised on Marathi market, where Sony Marathi and Colors Marathi both are already exist? Guess that, Colors Marathi will be rebranded as Sony Marathi and Sony Marathi will be rechristened as Sony Marathi Cinema.
