I really don't like speculating, and you're being super pessimistic.. but...
Retro Studios in Austin IS working on a new game. These are the folks who did the Donkey Kong Country Returns games, so they are pretty good with the 2.5D games. They also did the Metroid Prime games, so they have history with working with the franchise. It's entirely possible they are producing a new Metroid game.
Whatever game they ARE working on, they've been working on it since 2014 (honestly late-2013), so we might be due for some news. Just saying.
Nah, not pessimistic. Just being a realist. Nintendo has gone brain-dead. I have lost all faith in them. Aside from the Mini NES, I don't see myself buying anything Nintendo. It is a huge investment in a new system, just to play a handful of Nintendo games. Even more so when you take Zelda out of the equation for me since I haven't cared for that series since after Wind Waker on the Gamecube.
Like I said, I'm very, very happy for the Nintendo fans looking forward to the NX and are able to willfully jump through their hoops to play the games. I just can't do it anymore.
honestly i'd be right there with you if it wasn't for a few factors:
1) sony isn't saying anything about another handheld... the likelihood we'll never see a successor to vita is pretty strong, which means smaller japanese rpg companies who love vita will either
1a) continue putting their smaller rpg titles on vita forever (unlikely, but who knows...)
1b) move onto the nx for their smaller-budget portable titles
2) no one has copied animal crossing for some ungodly reason, and animal crossing is a huge love of mine that does, can and will sell a system to me. unfortunately.
3) nintendo handhelds get their own jrpgs... and it seems some other series are stuck to portables. story of seasons has not been released for a system so far, for example. i do like more casual titles like story of seasons, animal crossing, etc. cute, simple games that don't stress me out at all. SMT seems to be stuck on nintendo portables with SMTIV. monster hunter is on nintendo portables these days, exclusively, it seems.
but yes, you're right. i was absolutely burned by the wii. i still haven't really recovered from that feeling of 'betrayal'... it's a pathetic feeling, as they are a corporation looking to make money, but there you go. i had an n64... i had a gamecube... i didn't get a ps2 until AFTER i had a wii.
it feels like being burned, as a pretty loyal consumer of nintendo's hardware and software, to be forgotten.
and the wii u is a fucking catastrophe and honestly, i'm really considering selling mine too. there's a few titles tho that i'd be irritated at not just having. bayonetta 2 (with 1), the wonderful 101 was fantastic. i want to pick up that fucking stupid SMT idol sim rpg.... i'll probably enjoy it. i fucking enjoyed omega quintet and that is a horribly rated title, so i'm a trash consumer, clearly.
now, if it was today and i was looking at buying wii u, i'd be like... hell no. not worth it. but already owning the console...
that said, no 3d mario is bullshit. the new zelda looks fine, but i predicted it being a launch title for nx about a year ago, like twilight princess... and lo and behold, i was right. all i really wanted from wii u was a good smt x fe game like what the original trailer set up to be. i wanted an animal crossing. another 3d mario.
but the reality is, is my wii u will likely turn into a fucking wii game playing machine in the not too distant future, once i get a wii mote and nunchuck set. because i missed a lot of wii titles back then, and some of them were great.
but ultimately, the wii u was massively disappointing, and i have low standards. as it stands, i have one criteria for a new console purchase:
-5 games i want.
that's it.
and the wii u ended up just barely passing that. the xbone just barely passes that, but i'm not looking to get one until the price is lowered, i guess.
i was n ever an apologist though. ...i was pretty bitter halfway through the wii's life and never completely recovered. their portables, on the other hand, i'm usually fine with. and it is ONLY because nx is likely going to be the next portable system, that i will pick one up. if it wasn't, i'd not get it until not only was a new animal crossing confirmed, but it was on the market in the west, AND it wasn't a fucking miserable pile of shit like city folk was (basically, a clone of the portable game with a couple added things but nothing significant).
