Not sure if serious. Yes, it's advertising was clearly a #gamechanger. :/They had ads full of shitty dubstep to be made aware of the product.

Were they particularly good ads. Not imo. Does that mean that poor advertising is the core problem. No.
Would better awareness help? Yes. Would it fix that the Wii U is offering the answer to a question no one asked? No.
There's probably some form of irony in that people were making the same complaints about Vita marketing when it was flailing early on.
Advertising is not some magic bullet that fixes everything.
Yes, a marketing reshuffle was what altered the 3DS trajectory and not a 30-40% price cut. Canny advertising did it. :/
The USP of the 3DS is still not the sell of the system. People don't buy it because of a 3D screen. A non-3D 3DS would sell just as well, if not better due to the potential of a lower price.
USPs are only valuable if they address a pain point.
The touch screen controller does not for either the "core" nor the "casual." Advertising would not change this.
You say the market will care about the touch screen controller, they just need to promote it more? Why exactly should they care? What problem does it solve for them?
