nintendo has been doing this crap since the gamecube - why would you think it is all of a sudden going to change?
they are just a stupid company when it comes to consoles. there is so much money to be made if they just did it right. those of us who grew up playing the awesome games you are talking about, now are in our 30s and 40s and have a lot of disposable income and we are sitting here waiting for them to make these amazing games that we would eat up. but instead they are making stupid shit like animal farm and whatever the other crap that isn't the classics we want made for this gen.
What are you saying they did wrong with the Gamecube? They were more powerful than their biggest competitor, they beat Sony to the punch with an online adapter and "embraced" online at least as much as Sony ever did back then, they self-published as many mature titles as they could, etc. They continued making great games and courting other devs to do the same even if it meant throwing money at them (for example, Capcom exclusives and Metal Gear Solid Snake Eater).
Though people misattribute their failure all the time, they actually lost for a simple reason that had nothing to do with effort: the market wasn't big enough. It's the same reason the Dreamcast died (no, not piracy

). The DC died because too many devs and gamers waited for the PS2 and too few had a reason to get a DC after they had their PS2. Nintendo didn't do anything wrong to get to that point, they just failed to differentiate themselves from Sony and, when their slice of the target demographic wasn't big enough to justify porting the latest megahit, they got their butts handed to them again and again. That's why it's so crazy to suggest that they should change course and act more like Sony or MS to find success. They already tried that and history has proven that to be a failing strategy every time.
They didn't make the same mistake with the Wii and differentiated themselves plenty but the same people who THOUGHT they understood what went wrong with the 'cube
THOUGHT Nintendo was continuing down that same path and
THOUGHT that Nintendo was failing again (couldn't be further from the truth). It's cute to hear people so naive. Their ideas for Nintendo's failure sound more like a list of reasons why they like Sony/MS better ("ONLINE!" "NO WAGGLE!" "DUALSHOCK!" "ADULT GAMES!" "BETTER GRAPHICS!"). Invariably they completely fail to consider what would happen if Nintendo just became another Sony/MS to attract them away from Sony/MS. "Would you buy a Wii if the standard controller were a DualShock clone, it had an online service comparable to Sony, and better performance than the competition? You would? Really? Then why didn't you buy the GameCube instead of the PlayStation 2 the last time Nintendo tried what you suggest?"
These people make laughably wrong claims about Nintendo's failure to embrace online or how they have always had inferior performance. I sent my first email from a Super Nintendo that was more advanced than the biggest competitor (Sega Genesis/MegaDrive). They always had superior hardware until the Wii/PS3/360 generation and yet people think that this is the way it's always been.
