It's still all very rumory, so I wouldn't put much stock into it yet until something more solid shows up. I personally think it would be nuts to see them put specifically mainline Xbox games onto Playstation, like Halo, Gears, that sort of stuff, but I think it makes more sense to bring something like Starfield, which probably hasn't had as good of sales numbers as they wanted, or something like Sea of Thieves which is an 8 year old game at this point. It also makes sense to bring non-Microsoft branded stuff such as Indiana Jones over. This might be a good way to make up for some losses they've taken by doing the buyouts and haven't earned back quick enough.
Not that I personally mind either way, console wars are pointless. That being said, if this could lead to me being able to get Rare Replay on Switch (Switch 2), or PS5, I'm on board with that. I just want to easily play the Banjo-Kazooie games without having to haul out my Xbox 360 from the closet lol
