They have actually said it multiple times but for some reason nowadays "case by case" translates into "Yes"
And way before that, Phil actually said this:
Can you send me to a link where he said it? Please nothing vague. I want an outright quote that says Fallout and Elder scrolls will never go to playstation. Case by case means that some games will still go multiplat otherwise there would be no need to say case by case he'd just say nothing is going to playstation. Like right now you told me he already said it and then you link me to some twitter post from April where he doesn't even mention the games.
This is a massive purchase for Xbox. Xbox has been very very good at communicating what they are doing. Now they make one of the biggest purchases in gaming history and all of sudden they are very vague about what's exclusive and what's not. It just doesn't add up to their previous history. Listen maybe the games will be exclusive I just think it's very weird that they wont outright say it. I've also found it weird how everyone other than them is trying to say it. MS is very quick to respond to rumors yet here they are quiet all of a sudden.
They are about to release their console a long side PS5 after being outsold over 2:1. If you're locking some of the biggest game franchises in gaming history to your ecosytem only now is the time to speak. Keeping it vague is potentially losing you customers who might be willing to leave PS because of these games.
I think they are not saying anything because they actually don't know what they are going to be doing yet with regards to exclusivity.
But the lack of exclusive announcements seems to be a lack of confidence in the new hardware. If PS5 outsells Series X and S by the same margin that PS4 outsold Xbox One, then I highly doubt any of the big Bethesda IP will be exclusive as that will be a major own goal essentially.
On the flip side, it amazes me that people seem to think this move by MS was motivated by "console wars". Most casuals dont even know who the hell owns what. MS could have made this a HUGE thing if they included it in one of their press conferences by outright announcing exclusivity on an actual game. They chose not to.
Unless they actually do that, I'm willing to bet that MS has full confidence in gamepass and zero confidence in Series X/S or hardware in general.
