The difference being that Sony is putting things in place to catch problems with GAAS games and their review process of games in general seems strict these days. If Microsoft had a review process setup the way Sony does, especially with Bungie and GAAS games, Redfall would have probably been canceled years ago and the Austin location could have been saved from bleedout. There is also no evidence or reports yet that any of Sony's studios are being forced to do anything. In fact, throughout the years, Sony has been praised for allowing its teams the freedom to make what they want. But there are still consequences for failure.
Granted, that doesn't mean those games that pass review will definitely succeed. Deviation's game was seemingly canceled by the same review process that put Factions 2 on hold. In addition to Pixelopus' project being canceled and the team shut down. This isn't the first we're hearing of Microsoft's hands-off approach backfiring. Personally, when a company like Zenimax was having so many issues that they sold, I don't know why you'd let them just continue on as usual. Something clearly wasn't working before you bought them.
I could see them not wanting to rock a boat they just bought. Though honestly, the way 343 was handled, and the reports of The Initiative, doesn't inspire much confidence.
