Yes, the remaster is done by Tantalus.  The arcade port argument is pretty weak sauce since the thing was almost certainly in development for Wii U the whole time and aside from that most fighting games get arcade versions anyway.  The announcement dates and delays you listed are only relevant if you are asserting they delayed them after they were totally finished and those devs are working on something else. If they've been worked on this whole time the delays are somewhat embarrassing but not some argument that Nintendo is just making filler for NX.  Since that statement would imply that all or most of their teams are on NX and these games are totally done. Which we know is bogus for all but XCX which is in localization.

2014 wasn't the best, but it was way better than this.

Bayonetta 2, hyrule warriors, and smash bros combined is significantly better than xenoblade x plus filler games

Its my limited level of english tbh, I did not find an easier way to express that and is an expression I have read a lot on this forums without anyone feeling ofended so i use it too. But I was not trying to sound badly.

Thanks to some this thread derailed into Nintendo vs sony first party games comparison, so who started it?

I'm pretty sure I know the reason why that all started and who thought it was a good idea to bring sonys first party games in a discussion about nintendos exclusives games :P

nope that wasen't the reason :P

First, I was referring to the end of the year situation which is about the same kind of thing.  Small titles of mixed or poor reception plugging gaps.  

But to address your post, I would not consider Splatoon, Mario Maker, Yoshi's Wooly World, Fatal Frame V (despite its niche status a mixed reception), and in the case of Japan Genei Ibun Roku #FE to be filler.  Not as good as last year, still a pretty good one.  You seem to have confused the concepts "games I don't like" with the concept "filler." I would untangle those wires post haste.  The implications of each is quite different from the other.

he said late 2014. I could have included donkey kong tropical freeze and mario kart 8. 

splatoon released in late may (just like mario kart 8), mario maker is solid. but mario maker + yoshi + xenoblade + fatal frame does not match up to bayonetta + hyrule warriors + smash bros. Both smash and bayonetta were candidates for goty. I don't recall small "fill the gap" titles during late 2014.

Hyrule Warriors came out in September.  If you count that you have to count Mario Maker and Yoshi at the very least.
