Might this be what started that 16GB of RAM Rumor?

[Zappykins]

I notice in the recently released diagrams that there is an extra 8GB (Same as the original Xbox) tucked in by the South Bridge of the Xbox One.  (Where did it come from?) Incidentally the on die storage of the chip is 47MB which is @70% of the RAM of the original Xbox.  It's like there is an entire tiny little hard working Xbox inside the Xbox One.

One of the upgrades I really wanted them to included in the Next Gen Consoles was a solid state drive.  Some of the advantages to these are no moving parts, and they are super fast.  The downside is they are expensive, so what people do is a compromise have the operating system on a Solid State Drive and use a regular Hard Drive for most storage.  This give you quick responses to the stuff you use most and plenty of storage for everything else. I was disappointed when it looked as if both new consoles dd not have this feature.

Looks like someone snuck in a little extra 8GB of memory.

If you look at the schematic here.  Notice on the bottom left, past the Bluray and the 500GB Hard Drive, there is a little box saying 8GB Flash.  I haven't found any conformation yet that this is being used as a Solid State Drive, but seems to be a reasonable assumption.  What else would it be?  So there is an extra 8GB of rather fast memory on board.  Sounds like some rumors we heard before might have a factual component to them.

So with 8GB of RAM on board and another 8GB on a flash drive.  Since 8+8 = 16 and sometimes rumors are not properly overheard. Do you think this might be where that 16GB of RAM came from?  Seems like the most likely case to me.  And should help greatly with system performance.
