My first reaction was that the "Super Secret" document was fake, but when I thought more about it...this is a games company, not the Secret Service. They work daily in mushrooms and Triforces. It would not surprise me for staff to be light hearted and put Super-dooper-dooper hush hush on a document. And so much about the document seems right.
The biggest questions for me are SSB and SMU. We were told Smash was a ways off and SMU would be playable at e3. Having Smash on the list but SMU not seems backward. Over course, 3DS Zelda is also not there.
It could be that resources have been diverted and SMU is going to get extra work to be amazing but delayed, while MarioKart has been pushed up to sell systems. Smash is being done by Namco so perhaps they upped the effort there. This may have been easier than getting enough staff internally to get both SMU and MK out for Christmas.
I wasn't expecting it, but I can see Xenoblade 2 and Bayonetta 2 being out for Christmas. They are the games we've been seeing the most of. X had a lot going on its trailer, even multiplayer, vehicles, multiple enemies...they've also been working on it for what will be 3 years.
I don't think this stacked lineup would be overkill. It hits up various genres so the games won't compete against each other too much. And if they are saving MarioU, ZeldaU, Retro game and others for 2014 then there really isn't a problem with bringing the flood now, because they would have the titles to keep it going. That's even before considering the AAA third party support which Wii never saw. If Destiny and one or two others are announced for the system it will have a rediculous level of game support for the next 18 months or so. The kind of content we haven't seen since SNES days.
