Seemingly backed up by Tom Warren. Also Shinobi only says he knows of one game (A big one) not necessarily multiple so it may just be "game" and not "games". As it's a big one I'd probably lean towards FH5 or Starfield. Though Jez Corden says his sources tell him it's not FH5. Which means I hope it's definitely FH5.

Edit: Warren is saying it's not FH5. So... Starfield? Halo? What other "big" game could it be unless they're going to confirm one of their upcoming titles like Indiana Jones isn't exclusive but that seems unlikely to me.

My guess would be starfield or hellblade 2

I'm not sure Hellblade 2 counts as "big", definitely not sales wise. The only thing really big about hellblade 2 was the online discussion about it lol.

Considering the Starfield Expansion is coming out very soon that does seem like the most likely to me.

Just announce all of them comming to PS5 might as well just rip off the band aid and get the pain over and done with LOL

I would pay full price for Lost Odyssey but that's not exactly a "big" game so that's out. It's probably Hellblade 2, especially since that flopped hard.

I'm betting on Starfield. Expansion coming up, about to be a year since release, Bethesda going increasingly multiplat since Doom: The Dark Ages is confirmed for multiplat. The ABK deal scared MS into making Bethesda stuff exclusive lol.

Jez Corden believes it's something older like Killer Instinct or State of Decay 2. I've seen some speculation of MS Flight Simulator 2020. Over 12 million players and can be considered "big" to an extent.

I think it will be S.T.A.L.K.E.R. 2 since the PS4 just got S.T.A.L.K.E.R.: Legends of the Zone Trilogy.

It's already known that Stalker 2 is a timed exclusive, plus it's a third party game. I don't think that would count as the "next round of ported games" from MS.

Oh ok. I thought it was an Xbox exclusive. My bad.
