I don't really have the time to look (or even skim) through 30 pages of reactions, but I thought I'd chip in with my two penneth:
I couldn't help but be left convinced that Nintendo haven't got a bloody clue of where they're going with this. The message is muddled, contradictory, and the jettisoning of the 3DS would have me very worried if I owned one - they didn't even put a 3DS in the background of WiiU advert, yet phones featured prominently. A hint of a near-future admission of hand-held defeat, perhaps?
I was on board with the message of the Wii. The execution left a little to be desired though and after a couple of years I was thoroughly bored with it, but it was a step in the right direction for Nintendo. This just looks like two steps back, a half-mile trek sideways and a rollypoly out of the nearest fire escape.
Perhaps they'll prove my gut wrong, and really I'd rather they did, but I wouldn't be willing to put any amount of money on it.
You really don't see what they're going for?
Let me explain.
Okay, usually, E3 press conferences talk about concept/vision stuff that kinda bores everyone, with a little bit of sales charts thrown in for good measure, with the real exciting stuff, the software/hardware info, also spread around.
What Nintendo did with last night's 30 minute presentation was get the concept/vision stuff out of the way, so that they can focus on the software fully at the press conference.
Here's what you can expect:
1. The press conference will cover sales talk and a very brief review of the concept stuff at the beginning (10-20 minutes). The rest of the hour or 90 minutes or whatever will be devoted to Wii U games. They may put 1 or 2 game things before the sales talk, though, just to start things off well.
2. Within an hour of the conference ending, Nintendo's press site will have stuff up for games shown during the conference. In addition, a whole slew of games, both major and minor, that were never previously announced and were not mentioned in hte press conference will show up on the website. This year, that will include all 3DS content as well as Wii and WiiU content. That is how E3 goes for nintendo every year. Conference with a few highlights, and then a mega-dump on their press site that unveils many other new titles that are at E3 but weren't in the conference.
It's not that complex.
