TLDR: HBO’s The Last of Us adaptation might conclude with its third season instead of the previously announced fourth, according to HBO Chairman and CEO Casey Bloys.

Casey Bloy’s Perspective on The Last of Us Series
In an interview with Deadline, Bloys was asked if Season 3 would be the series’ last. “It certainly seems that way,” he responded, though he noted these decisions ultimately rest with the showrunners and could still change.
Adapting the Remaining Story

Fans of The Last of Us Part II know roughly how much story remains to be adapted, though the HBO series has expanded the narrative with original storylines and characters beyond the game’s core content.
This expansion means HBO could potentially stretch the material into a fourth season if desired—but the network appears to be showing restraint.
Catherine O’Hara’s Character

One uncertainty surrounds the character Gail, played by the late Catherine O’Hara. Following the legendary comedic actor’s passing last week, producers will need to address her character’s absence if Gail was intended to have a significant presence in Season 3.
Future Roles For Our Main Cast

Although fans may still be mourning Joel’s heartbreaking onscreen death in The Last of Us, Pedro Pascal is showing no signs of slowing down. The actor is set to have a packed schedule, reprising his fan-favourite role as the titular bounty hunter in The Mandalorian & Grogu, coming to TGV IMAX on 21 May. But that’s not all—Pascal will also suit up as Mister Fantastic in the highly anticipated Avengers: Doomsday.
