The analysis of their confused and weak presentation is dead on, but the bandwagon jumping about "Nintendo still has no online at all!" is getting tiresome. But that seems half due again to Nintendo, and half due to people not paying attention: on one hand, the Nintendo Direct video did suggest Wii U will have a lot of online social functionality, including some honest innovations. On the other hand, Nintendo themselves is not clarifying at all how the full online suite of Wii U is laid out and how everything interacts. At the primary E3 conf, they gave the direct impression that Miiverse was the only online functionality the system has, and the only interface there is - Iwata directly contradicted this during the Direct presentation when he noted that a conventional 'home screen' was available on the controller and could be swapped to the other screen, but naturally, they still have nothing to show whatsoever to end the confusion, fear, uncertainty, and doubt.
Nintendo's problem remains that they're incredibly tight fisted about giving information away, and seem to feel they must carefully shape image and anticipation as if pruning a bonsai. Unfortunately, that method is fast becoming patronizing and frustrating. Even if Nintendo does have their shit together behind the scenes, and is working on a solution that addresses most of the issues people have, their refusal to be forthright is causing everyone to write them off.
