I think is only a misunderstand, not important.
Wii U won't have 3 gb ... (for the above post).
Yeah it's because of the OS term, you thought and certainly some others as well, that i was talking about only the operating system, the "Windows", the software that the machine load into the memory to work + display the interface / manage all the features, whereas i putted marks on it ("OS"), talked about "software layer", features, etc. The OS in the strict definition of the word, obviously doesn't take all the RAM memory space my sources can't tap from, neither all the flash memory where it's stored, but it seems the OS + all the system features, in a v4 dev kit context, need a large amount of memory.
I'm sorry if it could have confused some people to believe that the OS is that huge, this is why i always added "features", "functions", after
But i think the flash dedicated to this OS is really telling about what Nintendo envision, at least at a particular time, for the Wii U. I mean, why reserving 512MB of a specific flash, separated from the other flash (as i understood) for your OS, if it will only occupy a mere 10/20/30MB like the current gen HD systems ? I think it's safe to assume, with this element combined with my first point (my sources talking about the ram memory pool they can't access + multi-tasking/pause-mode for games/a lot of features/their limited knowledge of the software layer until recently) that Nintendo will be ambitious, directly at launch or with planned following updates, for this department.

And for the RAM, yeah definitively not 3GB, nor 2,5GB.
