Yes, thank you, Kitsu. That's pretty much the reason in a nutshell.
Anyway, I'm not sure if you knew about this already, FinalSmash, but the Yoshi's Island handheld titles (with the exception of the GBA port of the original game) are not all that great. Personally, I find Yoshi's Island DS an enjoyable game (even though not too many people liked it), but I can agree that Yoshi's New Island pales in comparison to the original and the sequel because it didn't do a whole lot to innovate the game. Sure, we have the big Eggs, a few new Yoshi forms, and Yoshi gets to zoom across the room, but even adding a bunch of additional babies to change Yoshi's play style was a more original and fun idea than any of those changes would ever do. Besides, you get to use the babies in almost every level, while the other gimmicks are more or less one stop only in a handful of worlds. On top of that, even the level design of the DS game is a lot more interesting compared to the 3DS game (the lackluster extra stages from the 3DS game come to mind).
Sure, Yoshi is a good character and the 3DS is successful, but it does not change the fact that Yoshi's New Island is far from a good sequel and the studio that produced it needs to either shape up or ship out (especially considering that Artoon had a bad history of creating poor and mediocre games).
