Viacom18 might target digital rights of BCCI matches next, but leave all other boards & ICC rights, Amazon Prime might target digital rights of ICC tournaments.
Viacom18 will try to get both TV and Digital Rights of BCCI home matches, these have huge following among mass audience of the country hence TV rights r very important. IPL TV viewership is still quite good though i feel fatigue has set in among people and old kind of craze is lacking. Viacom18 will also try to acquire other cricket board rights, Sony will also have great interest in BCCI rights. Star/disney will try to get BCCI , Sri Lanka, England Cricket rights
