I don't think HBO max is launching anytime soon in India, even if they launch they won't have enough subs to recoup what Star India is paying them now... I'm an avid follower of HBO, but I'm 100% sure I won't be buying the Max Sub just for HBO content...
Also, FX has very good track record and is on par with HBO mostly in their quality.. They are ramping up production like hell just to feed HULU and in turn Hotstar.. 20th Television and ABC Singnature holds some of the iconic stuff which isn't currently available in India... They will surely making up their lost content from HBO with the Disney owned General Entertainment content.... So, I would still say they are worth 1499 for all the sports, and other content they will be offering once they lost HBO AS WELL.
