Stahp, foo!
Its a bad impression on the brand to STILL put games on the PS5 when they have more than enough games in their 1st party stable on their own. It also weakens the brand. If Bethesda games are still going to come out on the PS5, what reason do Sony gamers have to come over to Xbox? If anything, its a clear message to stay on PS5 until the games from Bethesda come over; at some point they will. That totally defeats the $7.5 billion dollar investment.
Lets not even mention that if Bethesda games go over to PS5, people are going to hound that MS is going 3rd party until the cows come home. Eventually they'll rant for Halo, Gears and every other 1st party title to hit the competition's console. Phil and Matt can deny any other 1st party titles are coming over to the competition all they want. NO ONE will believe it.
As I said, it weakens the brand considerably.
