>> Splatoon wasn't delayed

It was. All locked-on-disk content was released only in August-September period.

>> Yoshi's Woolly World and SMM never was confirmed for Q1 2015

Did you read the picture? Nintendo state them in a "1st half 2015".

 >> Project Guard and Robot were only tech demos

But officialy listed as a separate games. Project Guard is still 2015 game in Nintendo annual report.

And as far as we know, XCX is still coming this year...

@Samus Aran, Project Guard and Project Giant Robot are still in development actually; see source. Project Guard is co-developed with Platinum Games, although I don't believe the 2015 release window, we haven't heard anything since last E3. Project Giant Robot also mysteriously reappeared on the schedule this June, although it's release date is TBD.

I've already played and finished Yoshi's Woolly World, in Q1 2015. Splatoon still launched in May, the game was ready, you said yourself it was already on the disk by May.

SMM got one release date and it was kept.

I really don't know why do you continue to justify stupid Nintendo decisions on Wii U's current schedule. I can't remember any big 3ds game that was delayed this year.

Like I've said many times before -- Nintendo can't support two distinct hardware platforms any longer.

The development resources required for modern HD games are too high to allow for Nintendo to basically have to support two consoles. Yes, 3DS is basically a console now because it requires all the same franchises. And this will get worse next-gen because the portable will be capable of graphics equal to or close to the Wii U itself.

So the bar keeps getting higher and higher. It's not sustainable. That's when unifying the platforms is basically Nintendo's only choice.

Agreed. They either need to expand greatly, or unify into three or four super development teams and develop for a unified platform.

Regardles locked content Splatoon was realaesd in May and I played Splatoon in May, so you cant say game was delayed.

Also, Yoshi's Woolly World was released on all markets in 1st half of 2015 exept in US, I also played Yoshi in 1st half of 2015.

Well 3DS didn't had HD development problems like Wii U.

NoA confirmed that this Mario Tennis game is their big holidays title. If they can't push XenoX couple of weeks earlier, mean they would probably delay it too.

And still no sign of any Directs.

Don't know where you're pulling a Xenoblade delay from but it probably smells like crap there. A lack of info does not mean a lack of progress, and the game has a solid launch date already, something that almost none of the delayed games can claim. Star Fox would be the exception because I BELIEVE they had announced a date just before Mario Maker came out and they delayed it.

As for the second part of your comment, we really didn't get a "sign" of directs often. They were quite often surprises announced less than two days before they were shown.
