I do think that Nintendo could have provided a little more information during the press conference regarding the Wii U, meaning during the conference itself. There was information regarding the system that was clearly made available on the floor, but some of that should have been in the conference too.
However, I wasn't confused by it or thought it was the worst hardware reveal of all time or anything. I mean, would it have taken a laser show with Slayer playing to say "this is our new console and its hardcore" for everyone? Nintendo seems to be veering into becoming a company that utilizes "hands-on" experience to sell their technology while providing "enough" of the technological talk to get the tech-heads interested. They always stress now that selling their systems requires getting it into the hands of people to try it out. Because that doesn't do so well for crazy hardware people that need to know what minerals make up their components, it falls flat. For me, and for many people who have no idea what E3 is or even care, the right information will get to them easily and in a polished manner, and they'll get to try out everything, in-hand, to see if they want it. I wasn't sold on the Wii idea either until I tried one a few months ago, and now I want one. There are just different audiences, and Nintendo's challenge is finding the right balance of their desire for hands-on experience and casting out information for the tech heads and pixel counters.
As objectively as possible, and I watched this with my girlfriend who literally has never played a game in her life, and though she wants a Wii for Wii Fit and all that and knows about the console, we both knew that Nintendo was talking about a new console in the press conference. Besides all the developers saying that it was a "new console," she pointed it out during the first video, right beside the TV, because I was missing it looking at what the tablet was doing. We both could tell it was a new system.
I also liked how they showed instances of the games from casual (that first video) to "hardcore" (the 3rd party developer video). Getting EA's blessings from the CEO was also nice as well, and it showed a commitment to the new console.
Now, after the conference, more news has been coming out talking about the console and the tablet, some of the games being planned for it, and some hints that can be made from things people are saying that may or may not be anything of worth. But, E3 doesn't just end at the end of the press conference; a lot of floor time and interviews have taken place and more information will be coming in, from all the console makers and game developers.
Do I think it was rushed? No, but it is early hardware, and it has gotten people talking in all manners of ways. That's a start. Nintendo just has to continue work on this thing, keep providing information about it, feeding people hints and all about what to expect, leverage traditional media to get the console in people's minds, and they will do very well.
