But it won't stop me enjoying the curently available nintendo games for Wii U and 3ds and some that are about to release on the future.

PEACE! 

All this bashing of Nintendo is just sad. That's what they get for releasing a console with fun games.

Agreed.

This holiday is gonna be sick regardless

a bad E3 doesn't stop me from enjoying their games either

The 3DS had a fairly good E3, it was just that the Wii U didn't.

That being said, the lineup for the rest of the year is still quite good and varied, so I don't have a problem. I should be good up until SMTxFE launches, and if there isn't anything planned after that, I'll be upset.

Was it disappointing? Yes. Was it terrible? No.
There is still a lot of great stuff to look forward too. Star Fox Zero looks like it'll be a great game. I'm very excited for Mario and Luigi: Paper Jam and Fire Emblem: Fates, and The Legend of Zelda: Triforce Heroes looks like it'll be a fun 3DS Zelda game, (and the first one with online multiplayer might I add)
I'll admit, I was definitely expecting more than what we got, I was let down, especially compared to last year's E3. But what we did get, I thought was decent enough and I look forward to these games coming out this year and next year.

Don't try to defend Wii U , i own one but it is a freaking disaster. There isn't a a single game to buy after Bayonetta 2 release.

The problem is not this year, the problem is the entire gen:

Wii U launched on 2012 and so far until at least 1half of 2016 (almost 4 years after launch) we don't have Zelda, Metroid, Fire Emblem, Paper Mario, Animal Crossing, etc. Do we have a lot of games? Yes. Do we have what we've been asking for? No.

It was bad, but I will still play and buy games for my Nintendo consoles.
But not Amiibo.
