Labels like that are actually pretty common on internal documents.  Though not usually plastered on it watermark style but rahter in the header or footer of the document.

Nintendo is unlikely to have two "different" models with different haddrive/storage space--especially with the generally small difference between 250 adn 320 GB.  

"Custom" Blu-Ray sounds like something Nintendo would do--as in, crafting their own proprietary disk (probably with Matsushita again) as they did with GameCube and Wii where they built faux-DVD technology so Nintendo wouldn't have to pay for the rights to use actual DVD's.

Exactly what I was thinking.

I've seen it done multiple ways, sometimes including schemes to prevent the email server from sending out draft or internal documents; these tend to be easy to get around but are there to prevent people accidentally sending out the wrong version of a document.

I think that this spec sheet is probably a fake, but believe that it is a decent fake because it seems to be a middle of the road prediction of what Nintendo would produce; advanced enough hardware for those that believe that Nintendo will produce a significantly more powerful system than the HD consoles, and old enough hardware for those that believe Nintendo won't be producing anything remarkably powerful.

Except that the Gamecube's disc wasn't crafted to avoid DVD licensing fees, it was Matsushita's proposed DVD format which was rejected by the consortium; and it was likely that Nintendo picked it as a format because it had far lower latency than DVD and would be difficult to pirate (being that it wasn't a standard format). Ultimately, the amount of money they spent licensing the technology from Matsushita was probably similar to the cost of licensing DVD, so it is unlikely that was the main reason for choosing the format.

Essentially, it would be like Nintendo using a modified version of HD-DVD in their next generation system.

According to the OP, the Wii is using XDR2, better than the PS3's XDR.

Won't use it.  Rambus can't find anyone to license it out for manufacturing.

I am think maybe companies could start doing that with their promo material, to get it to circulate among the Interwebnets.  Yes, this is me taking a cynical view of things, but seeing it as cool in a twisted sort of way.  In short, if you want something to get circulated, have it have a watermark, "for internal use only".

which is another clue to the fact that this is fake, everything else is generation old tech that fits with Nintendo's current trend of using tried and tested tech in their devices, why go for extreemly expensive RAM that no one uses and pair it with a last generation CPU? That and the fact that it has the rumered 512MB of RAM but also uses 1GB VRAM even tho past nintendo systems all have more shared RAM and a small amount of VRAM and other systems use equel ammounts.

The only improvment over the PS3 would be more RAM. Aside from that I would say it is close. Cell may still be a better chipset though.
