I think there will be S tier SKU also. Using Magnus AT3 with 40-48 CUs, Slightly less powerful than PS6 but designed for 1440p, just like how the Series S was supposed to be. Magnus is the CPU SOC with media die and NPU, it can be paired up with any of the 5 GPU dies. Like how Series S and X both share the same CPU, just slightly different clocks.
And pricing might be similar to the Xbox Ally configurations. $599 and $999
So PS6 handheld at $499, Xbox Magnus S at $599, PS6 at $699 (without disk drive), and Magnus X at $999. Effective cost of PS6 could be $800 including a disk drive and Stand.
I think there will be two SKUs for Magnus first party consoles, X and S that act as the baseline. So two SKUs for devs to optimize for, for both Xbox and Playstation.
That's why MS won't mandate handheld support for devs, and simply rely on the handheld Verified program, Play Anywhere, and Console library BC and FC on AMD RDNA5 chips to run games as the devices become more powerful every iteration.
ProElite said OEMs will be doing the higher spec variants of the MS first party consoles, like higher storage, ram, clocks etc.
OEMs will also be doing the rest of the devices in the portfolio, so Xbox PCs with Magnus AT2 and Magnus AT1, Xbox Laptops with Magnus AT3 and Magnus AT4, and Xbox Handhelds with Magnus AT4. While Xbox Cloud runs on Magnus AT0.
The way xcloud works currently and the way MS would like it to work, (similar to Nvidia GFN), basically requires there to be 1440-1080 versions of games optimized by the developers, in order to reduce energy and cooling costs.
