they seemed pretty preoccupied with destiny 2 dlc. they only recently finished all destiny 2 development like 3 months ago. if they had some super secret major project that would've won the publisher big money, it'd basically have to have been started september 2018 and finished april 2020, which is pretty unreasonable. they could've squeezed a short project like another destiny DLC into that space but they probably realized that it wouldn't be much of a profit for themselves or activision anyways.
i dont think this is some sort of bad omen, it's just the natural end of the publishing lifetime. not enough time to make a best selling project. activision and bungie both realized this fact and decided to stop wasting each other's time and money, they already reaped every cent they could out of this lucrative contract. maybe even bungie got more out of it in the end because they got paid for 10 years worth of publishing rights but only gave out 8 years of it
