Least we got a Skyrim again  

For real though, Skyrim and GTA 5... used to have so much more faith in Rockstar (off topic ik), but it's pretty shameful how far they've fallen (not money wise obviously). 

Hopefully this gen we get ES 6, GTA 6, new IP from Rockstar (lol), SR 5. Shaping up to already be better than gen 8. 

In theory at least, there should be no difference in framerates. MS asked developers to target native 4K 60 fps on Series X and native 1440p 60 fps or 1080p 60 fps on Series S (depending on their engine and how resolution scaling friendly it is). Series S has roughly 33% of the GPU power of Series X, while 1080p is 25% the resolution of 4K (meaning Series S has power to spare if devs aim for 1080p on Series S) and 1440p is roughly 44% the resolution of 4K (meaning that Series S is a bit light on power to be aiming for 1440p, at least on paper, though some engines scale better than others). 

Chances are, framerate will be the same on both consoles, with developers scaling down resolution and certain graphics settings (especially texture, world geometry, shadow, and character model quality due to having less RAM to fit those things onto) on Series S in order to achieve the same framerate on both platforms (at least as an option, with some devs possibly having both a graphics mode and a performance mode on Series S). We already know that Falconeer and Gears 5 have 120 FPS support on both Series S and Series X, so that is something at least. Though Dirt 5 has an optional 120 FPS mode on Series X that doesn't seem to be available as an option on Series S (which is 1440p 60 FPS on Series S, compared to 4K 60 FPS for the 4K mode on Series X). I imagine most multiplayer devs will aim for the same framerate on all Xbox consoles for balance reasons, so for instance Halo Infinite should be 60 FPS on all 4 platforms for multiplayer (XB1, XB1 X, XSS, XSX) with a different resolution target and different graphics settings on each platform to allow each to hit 60 FPS, while later multiplayer games once Xbox One support is dropped should be the same framerate on both Series S and Series X in most cases. Singleplayer games are more likely to have discrepancies I'd say.

Insider says MS is close to finalizing a big acquisition deal. Says he thinks the announcement of this acquisition may be a "save the best for last" situation ahead of the launch of Series S and X, which would seem to imply that the acquisition is an even bigger deal than the Zenimax one.
