It's the fact that Nintendo (while constantly making profits over and over) , neglects a portion of their potential userbase by dumb founding decisions in relation to power, multi-media functions, online integration. And it's somewhat baffling.
The Wii would have mopped the floor with MS and Sony in PS2 style and made even more ridiculous profits if it had a quality online environment, multi-media environment and compatible power with the PS3/360.
Wii U seems like more of the same and I think it's the wrong strategy at the wrong time for this upcoming generation. Wii was a perfect storm of intrigue, disappointment (In past Gen leader, Sony), lack of trust in (MS) and lastly a very competitive price in an insanely high priced market.
That 'different' crowd that Nintendo has picked up this generation we are somewhat unsure of their long term buying patterns, their adoption of new hardware, more costs into their gaming. I feel like it misses the mark of that crowd and it does the typical Nintendo move of missing that PS3/360 core crowd as well.
but i think you miss the point right there if the wii had all of those things from the get go obviously it would have been priced comparatively to the other consoles ( or maybe higher ) and i'm quite sure that had that been the case it wouldn't have been as successful as it is or maybe even less successful than the other two
