Rumor: Another Xbox Franchise Could Be Getting Master Chief Collection-Style Remaster This Year
Many players first guess is likely to be the Gears of War series, which wouldn't be the first time a series collection has been rumored. It can be argued the series is the second- or third-most recognized Xbox series, depending on how some players may view Forza, and has a game released on every Xbox console since the first game on Xbox 360. It also makes sense if Xbox is working on Gears 6 and is looking for something to placate players until it is released.
Another option is the Fable series, which has not seen a mainline entry released since 2010's Fable 3 on Xbox 360. A new Fable game was announced at the Xbox Games Showcase in July 2020, though little else has been said about the game since. Players can argue a series collection would be a smart way to build up to the new game's release by re-familiarizing players with the series.
There's also a chance Xbox may look at its more recent acquisitions, namely Bethesda and Activision Blizzard, for a series worthy of the Master Chief Collection-treatment.
