So Valve did update their Steam Deck website in regards to the SSD.
Because it says socketed, most likely it is similar to Xbox where if you can get to it's location, you can probably replace it but because you have to remove quite a lot of things, it's not intended to be user replaceable and probably will void the warranty.

The performance increase compared to a 6900XT is impressive and the main thing that increases is the memory bandwidth. If the 6900XT had a similar bandwidth to a 3090, I am sure RDNA 2 would have taken that crown, least in Raster. But for now, if you got money to spend, Nvidia continues to give you the most amount of features.
We don't know the price of this as I believe it's OEM only for now. But we know it's going to be more expensive than a standard 6900XT and at that point... May as well get a 3090!
