Zee Chitramandir will definitely movies channel because Chitramandir means cinema hall. If it is dedicated channel for plays and dramas then the could named it as Natya mandir or Rang mandir not chitramandir. So it definitely movie channel. And one more thing it will not OTT platform because All marathi movies which are with Zee are available on Zee5 so they couldn't launch another OTT service and it also will not an service channel for any DTH because Zee Plex is already there on which marathi movies are currently premiering so it will be satellite tv channel no doubt.
Sun Marathi should remake Pavitra rishta (remake of popular tamil serial don't know name) in Marathi with changes it will be great but I want Sun Marathi to be original swamake channel with only some good remakes.
Yes Zee Chitramandir may be VOD Service and Zee Chanderi will be a new GEC/movie or mostly it will be rebrand of Zee Yuva after rebrand they will show New Serials, Shows or else they may keep it as rerun channel.
