Sony's Investor Relations Day 2021 Presentation seems to spill the beans on
plans to bring
Uncharted 4: A Thief's End to PC (thanks
Gematsu). Included in the slides is one outlining "new growth vectors" for
PlayStation Studios. This has a section on "off console" releases for PC and
mobile. The PC heading references the success of the PC release of
Horizon Zero
Dawn, and lists two more planned PC releases:
Days Gone and Uncharted 4: A
Thief's End.
