That was a poorly thought out article. He praises Nintendo for showing a snippet of the new Zelda game that had no gameplay, and then claims that Sony "Shat on" E3 by showing a clip of Uncharted 4 with no gameplay.

"Nintendo decided to try and win people by actually showing their games, and when they had nothing more to show ( Zelda U, as an example), they sort of let it be and tried to avoid talking about it."

"Everyone I know right now seems to feel that Uncharted 4 snippet we saw is pretty much the closest thing to reality we have ever gotten - and yes I have to admit it looks really good. Naughty Dog's track record for pushing great realistic visuals is on full display. The problem is - we never actually saw any gameplay."

"Games should be shown off with gameplay, not snippets where we can only guess if it's actually real or not."

"The Zelda U reveal reminds of this greatly. I can believe what I saw on screen is from the game visually. However, they couldn't show off gameplay, so they stopped talking about it."

"Is it so hard to not overhype something before you can prove it?"
Fanboys hype up games, not E3 presenters. Nintendo showed a clip of the new Zelda, and Sony showed a clip of the new Uncharted 4.

yea they did that for one game to show off that it was open world this time.  Next year I guarantee you that they'll have gameplay.  They'll probably spend 3 hours playing in hyrule field showing off the sights.  The difference is that every Sony/Microsoft game showed fake graphics through cutscenes, almost every Nintendo game by comparison almost exclusively showed real gameplay.
