I see. No proper Castlevania and the lack of a sequel to TWEWY are really sore points for me too, as well as what happened to RE:R2.

I don't really have that many a game for my 3DS when I bought mine in Oct 2013, I bought mine for Pokemon Y at the time and also grabbed ACNL, FE:A and then the following year I bought Link between Worlds and got gifted Super Mario 3D Land, that's 5 games I've had and played since 2013-2014, I suppose I could count having Sonic 1 (Master system version) and Sonic 2 (Gamegear) digitally.

I do wish there were a few more games out there to entice me, I am wanting to grab the latest MH but I'm waiting for N3DS to get a slight price drop, trade in my current 3DS and use that money towards the new unit. I'm also wondering if their next new handheld will be announced either next year or 2017, it would probably make snese for the lack of big titles now if they were to announce a new handheld in the next year or two.

That's understandable. 

For me, personally, no games could ever release for the 3DS ever again and I'd be fine. There are so many games that have already come out for it that I want to get, and I'm already really happy with the small library I have. I feel that production for 3DS games has slowed down due to it being near the end of its life. A similar situation happened to the DS in its final years, as well. This is also because most handheld developers jumped ship to mobile platforms, and Nintendo handhelds have almost never gotten western support.

50mil 3ds sold, not killing them. We'll see HHs still inthe future, even if only its Nintendo

3DS is tracking around 30% less than its predecessor during the same period of time. That's a hell of an impact. If the next Nintendo system follow this same route it will sell 35 million during the same period of time. It's not critical yet but not a pretty picture for the future of the handhelds.

but look at the OP, says we got games before so it has nothing to do with the decline in this discussion. HHs arent dead even if the next HH sold at 35mil.

Of course HH market won't be dead but look at size of Nintendo. Ask them if they're happy with this situation. Can you imagine the next Nintendo HH selling even less? Is that healthy from a business point of view? Any company wants its products to sell more than the previous products, specially big companies like Nintendo.

Same here--really not much for me on the system for the last year or so, whereas there were tons of games in the first few years. With the install base growing you'd think the point would be to actually INCREASE output as time went on. But game companies are just a conundrum as a whole, so I do my best to just not think about it.

New console is coming soon, devs are probably already working with dev kits for NX. We'll see a few more surprises for the console, no doubt as we did with DS. However, the lack of Japanese imports is also hurting the US 3DS library. 3DS is almost old by today's standards. It's been out for what, 4 years now? We'll see a couple new games at E3 that'll take us up to 2016/2017 and by then 3DS will be taking its final bows.

3DS's is library is great. I do however think it severely lacks the small experimental games GBA and DS had. Indie developers who specialize in experimental retro looking games are roughly the same size or smaller than the teams who worked on previous handhelds. Though they already found their audience on PC, consoles and sometimes Vita. It's tough for Nintendo to juggle two devices with minimal support from small developers.
