I have no idea what is inside the XBox DevKit. But DevKits require more memory than the end product simply because there has to be a lot of debugging software running all along. So MS might have chosen the odd way of memory setup in their kits.
Rumours have it that the MS SoC is considerably bigger than Sony's (rumoured roughly 370 vs 310mm^2). Nobody knows if that is due to additional memory controllers or a lot more CUs or a combination thereof, or simply a rumour.
I'll also surmise that the new SoCs use all kinds of on-the-fly data companders (compression and decompression hardware). That way, newer chips save a lot of bandwith compared to last gen chips. So even a "measly" 256bit bus is good enough for full 4k.
I'm pretty sure Sony will use a 16GByte 256bit gddr6 system with a small ssd/(possibly ReRam) proprietary thingie down the line for streaming in (graphics data) and out (video streaming). I'm not so sure Anaconda will only have 16GBytes, but in a few months we will know the answers.
