Based on a recent leak, it seems that Halo’s developers might be working on a brand new two series expansions. A leak has discovered that Halo Infinite will be released in a total of 4 different chapters that will be released in a span of a decade and that two new Halo spin-off titles might be in the works.
This has been first stated on a known leaker’s Twitter profile, which tends to guess things right. With that said, Halo Infinite and its release will be a resemblance of the Master Chief Collection and its release fashion.
Leak: Halo Infinite will function similarly to the Master Chief Collection as 343 plans to release 4 "chapters" in the decade of supporting Infinite. 2 spin off titles are currently in the planning stage.
