Activision is not a company I would put any money or faith into right now. What do they have going for them besides King?
They don't have Destiny anymore, and it's not like Destiny 2 was a real success anyway. The reception of the game was not good, and the expansion pack clearly failed to meet expectations because the base product was not a good experience.
Call of Duty is past its prime, they didn't manage to outpace last year's game even with a Battle Royale mode that launched when Pubg's reputation had soured and people were looking for a different game.
What else does Activision going for them? Almost nothing. Crash and Spyro aren't franchises worth anything in 2019.
Blizzard is in complete freefall, all of their franchises are suffering. BFA is WoW's lowest point ever. Hearthstone has long since passed its prime. HotS is dead. Overwatch is clearly suffering massively from the popularity of games like Fortnite, Pubg, and now Apex, and is passed its prime anyway. Starcraft is dead. Diablo had one of the worst public reactions to a game announcement ever. The only hope at Blizzard right now seems to be their "incubation" team working on other new mobile games, but Diablo Immortal is not a good first impression of that. Classic WoW could be big, but its running on a Frankenstein of 1.12 imported onto the 7.3 legion client, they could easily fail to match the original experience and sour the playerbase instantly.
