Hotstar X is an inside name used by developers. The name 'Disney+ Hotstar' will continue. The current beta testing version doesn't bears any studio/brand categorisation. Probably they will introduce tabs like in this picture. But if they adopt this model then a 'Hotstar' tab will get added replacing 'Star' tab. And all Star TV shows, non Disney+ shows like HBO, FX etc get sorted inside this. Currently the app is being like Hotstar with Disney+ inside. Will it change to Disney+ with Hotstar inside
