Absolutely right about Nintendo not marketing to a cohesive demographic. On one hand, the graphics will be significantly better, which will appeal mostly to "hardcore" gamers, but on the other, they have a bulky, expensive controller which is the most un-ergonomic piece of crap I can think of, appealing more to trendy demographics and families seeking a more interactive approach to casual gaming. Considering the recent /. thread regarding the average gamer age being 38 (I personally think it's in the twenties, but the point I'm making is still valid), Nintendo is seriously missing out on the "hardcore" gamer demographic, especially with the fact that even the well-established games with potential such as Zelda cater to preteens with the storyline and level of difficulty of the fighting system and puzzles. Wii U's attempt to appeal to everyone is going to consequently appeal to no one - the family demographic being off-put by the cost resulting from the increased processing and graphics, and the "hardcore" gamers being off-put by the controller.
And if that post itself was not cohesive, my apologies. I'm drunk off my ass.
