EBA may have been DS only but Rythm Tengolu had Wii and WiiU versions (and that was a handheld franchise)
Small correction, there never was a Rhythm Tengoku game on Wii U (unless you count the Wii Download version of the Wii game...).
In my country, there were widespread reports just before the 3DS launched that the 3D technology in the system would hurt the eyes of small children. The system NEVER recovered from that.
I hope you're not from the UK, and that you're not referring to that one lone article from the Sun or whatever other garbage trash tabloid, because that was just them tring to stir sh*t up and run on the controversies (which is the only thing they know). That never amounted to anything, at all.

Nintendo themselves are somewhat moving away from 3d with its 2ds & also upcoming new 2ds ll. if they still care about 3d, the upcoming model can just be for example ultra 3ds ll instead of new 2ds ll
They're not moving away from anything... well, they are, but the 2DS / New 2DS XL are not proof of that (Switch is).
2DS is a super cheap entry level model for kids... the very users Nintendo advise against using 3D for.
New 2DS XL is, well, the New equivalent of the 2DS, for players who want something that doesn't exist yet: a relatively cheap but powerful 3DS model with big screens. Wouldn't make sense to have an Ultra 3DS now. And adding 3D to the 2DS XL would just make it a New 3DS XL with a fancy design (and 2D screens are much cheaper anyway).
Honestly not sure I understand the whole debate about 3D and 3DS sales. 3D never really had any sort of impact on 3DS sales. Positively or negatively. Vast majority of users were pretty apathetic about it, and very few bought a 3DS just for the 3D or didn't buy it because of the 3D (I guess you could argue some people didn't like the compromises required for 3D, but the thing is, people chose to buy/not buy the 3DS based on the games on offer and/or price). That's why you haven't seen any real outrage or even debate about the lack of 3D with the Switch, even from 3D enthusiasts (like me).
That's pretty much the thing about 3D and the 3DS: originally designed as its major feature, 3D remained nothing but a nice extra/baggage (depending on your point of view).
