I'll just say they're not doing themselves any favors in the way they market their products or how they present some of them. The last time I felt a Nintendo system was for "everyone" was the N64. The image of the GC turned off many people - although it didn't bother me since I played it more than my PS2 even though my GC collection is about a 1/4 of my PS2 software library.
The way how they market the Wii U is another thing. I just don't get the sense it's a machine adults can enjoy, but I am an informed consumer and I know better, so these things don't sway me. The less informed and the highly impressionable probably won't see it that way ...
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
