Typical "innocent" article by Tom Philips.... and the worst thing is to involve Rich in his usual clikbait console war.
Xbox currently has a lot of projects using UE5 for years. (Gears E-Day, PerfectDark, Avowed, ProjectMara, SOD 3, SOM, Clockwork REv, EverWild, etc...)
It's funny that the idea he wants to incite is that the change from Halo to UE 5 should be specifically to facilitate a port to PS5 when the reasons go much further and began several years ago.
Halo on PS may well be a reality in the future. But that the change to UE5 is for the sole reason of bringing the franchise to PS is ridiculous. Simply SSengine was outdated, hiring trained developers was very difficult, and upgrading the engine and matching UE5 in capabilities was expensive. Simply 343 has made the same decision and for the same reasons as CDProjekt by abandoning the CRed engine for UE5.
