It's just bad because you always know what they will show (and even more). Stop reading through the internet 365 days a year and expecting huge things @ E3.
There are almost 10 Wii U games now that I will buy. Which is enough for one year. And I like that I was allowed to see some videos of the games before release.

If I was responsible for PR, I'd never tell anyone about a release until 1-2 months before it's happening. That way you keep hype. And it's P(!!)R, not business R.

I think Nintendo did mention in the direct there was dev diaries and trailers in youtube and reggie mentioned before e3 that there will be a lot of content in the channel. Regardless these dev diaries are quite good and go in sufficient detail. People go check themo at.

Pretty much every game they release has local co-op and it's not selling many systems.

It wasnt the best at all for nintendo, all it told me is i dont need to bother with a wiiu until after mid 2014 or sometime in 2015 and it will be a much better experience.

I would say look at the Developer Directs. Hopefully that will clear things up for you.

As a Nintendo fanboy their E3 showing satisfied me, but I feel like it didn't succeed overall in showing why anyone beisdes the diehard Nintendo fans should get a Wii U. The two big disappointments for me were firstly, not having a fully 3D Mario platformer. Seriously a 2d/3d hybrid like 3D Land for the Wii U makes zero sense. Especially with NSMB2 and NSMB U still being relatively new games. The last thing Nintendo needed was a 2d Mario of any kind. And yeah I know it's not strictly 2D, but it's not strictly 3D either, which is what it needed to be. Those are always the Mario games that really show off what their system hardware is capable of. I don't feel like 3D World will do that whatsoever for the Wii U. It will very likely be an excellent game, but it also looks like it could easily be done on the 3DS, and would be a better fit for that system. The 2d/3d hybrid worked so well for 3D Land because of the stereoscopic 3D of the 3DS, which Wii U doesn't have. So that was a massive mess up on Nintendo's part in my opinion. 3D Mario is always their chance to show what their home console is really capable of, and I think they missed that chance with 3D World.

Second big disappointment was DKC Tropical Freeze being Retro's big WIi U project we've heard so much about the last year or so. Kinda tying back to 3D World, does anyone really need another 2d Nintendo platformer right now? Yeah they're great, but they're just becoming sooo over-saturated. And a DKC sequel was always last on my list for what I hoped Retro was working on. Even Prime 4 would have been a lot more exciting and fresh since its been awhile now for that series.

Was most happy with X, Bayonetta 2, Smash Bros, and surprisingly Mario Kart 8, which actually looks like a much needed change of pace for the series. The whole Mario Kart Galaxy feel definitely has me intrigued.

I think Nintendo decided against holding a traditional E3 conference for a reason this year. Through their Nintendo Directs they have been revealing new games and other major announcements every other month for a while now. Perhaps we should stop thinking about E3 as THE major event where Nintendo is gonna blow out all the big news. So in this regard I don't feel Nintendo is out of touch.
Nintendo fans also seem to forget sometimes that Nintendo is a business. So while I can totally understand why fans might be disappointed by Nintendo playing it really safe, it's quite understandable from a business perspective. Nintendo might deny it but it's quite obvious to me that they are trying to maximize their ROI with games like Mario 3D Land for WiiU. And until sales of WiiU improve drastically I doubt their strategy will (or should) change anytime soon.

Totally agree - no Wiiu game should have the word 3D in it's title. 

Untill this point, for the few games they released, it hasn't worked. I would say it's mostly due to mixed message to customers.

The new 3D Mario should be backed up with a solid message and a marketing campaign (if not a pricecut).  If this fails, then Nintendo has a big problem.

I'm assuming you didn't watch Nintendo's 2008 E3 then if you believe they're out of touch.
