"WiiU was poorly placed in Japan, with many customers getting their Nintendo fix on the 3DS after its sales had improved.

3DS launch in Japan was terrible, just as it was everywhere else in the world because early support was borderline nonexistant, and the media had run with stories of kids getting headaches and/or seizures from the 3D screen for weeks prior to its launch."

Psst, 3DS was doing fine when the WiiU first launched, hence my comment, you misunderstood it entirely.

"Vita launched with a high price and against the relative success of the thriving (in japan) PSP that not only had an expansive library but cheaper games"

if I didn't read this clearly.. couldn't I just replace psp with ps3 and vita with ps4? Exactly. Ps4 has literally no games if you already own a ps3. Well no relevant games. 

PlayStation 3 games cost the same in Japan as PS4 games, in addition to this, the Vita was also contending with the now-successful 3DS too, What home console is the PS4 contending with exactly?, You can say PS3 if you want but a large portion of the PlayStation fans in Japan are looking for something new.

"For all of the Nintendo systems, advertising in stores, on TV and on the streets was also virtually non existant, so the demographic most likely to buy it did not understand what the product even was."

Not for 3ds.

Oh im sorry, I didnt know you were the same as me and have spent the last half of you life actually LIVING HERE.
Advertising for the 3DS in Japan was almost non-existant when it launched, there were no train station ads, very few TV commercials, very little magazine space, very little coverage on TV.

"The huge difference here is that the entire country has seen the success of the PS4 elsewhere, and the media has nothing but praise for the console, with extensive advertising in every store, on the streets, in subway car displays, on TV and radio."

That is probably the biggest hyperbole statement ever. The entire country doesn't know or even care about the ps4. Heck not even the USA cares that much. It's success in other countries has nothing to do with it's success in Japan. The determines the success in a Japan is games and where the market is going. Mobile systems are the future as Japan as already spoke. Even in ps3 best days it was selling anywhere near the handhelds. That's ds and psp. Advertising isn't going to change that. The games that relevant are locked on handheld.

TV shows here are very patriotic, as are magazines, they have been bragging about the success of the PS4 in countries outside of Japan since the day it was launched, many of the large electronics stores have been taking advantage of it with signs such as "best selling console worldwide" and "1m sold in america in a single day", the hype is here and the hype is real, sorry to burst your bubble.

"But hey, don't take my word for it, see for yourself in a week when the sales are in."

After seeing bandai comments it seems like even he sees it's fate. Bandai knows more about the market than you or some friend that's excited. When says come, I will be back to say I was wrong or right.

And if I am wrong you will get a full apology, however I suspect you will be the one saying you were wrong.

Boy you just love getting banned don't you?
