Blizzard's president has said a potential follow-up to Diablo 4 - Diablo 5, if you will - won't spend as long in development as the current game did.
Diablo 4's development timeline was anything but smooth. The game reportedly went through multiple iterations at Blizzard, with multiple personnel stepping into and departing from leadership positions. In all, Diablo 4 took roughly a decade to develop, from initial conceptualization to release.
