Figured I'd ask an "Elephant in the room" type question!
Basically, we all know the Switch is using a modern NVidia graphical architecture (it's friggin' Vulkan compliant guys!), and we know that major industry game engines like Unreal Engine 4 and Unity are both onboard for Switch support. On the other hand, I think things are shaping up that it's in no way going to be a brute strength hardware powerhouse.
Then we throw in Nintendo's historical difficulty in creating a platform that third-parties enjoy and... well, do you think they'll make any progress on the switch?
I mean, YES, we MIGHT get a Skyrim port, there's rumors (grain of salt alert!) of a Dark Souls port... but are those false signals or wishful thinking?
Personally, I think the Switch will make significant strides in making it TECHNICALLY easier for third parties to support it. Modern game engine support will have a very noticable effect on third-party support I believe.
HOWEVER, I have very tempered expectations on any idea of a 3rd party resurgence overall.
I think we seem to have a lot of third parties excited to port older games, which is nice but we've seen historically is not likely to set anything on fire (see: Wii U year-old ports).
Also, I feel like we're seeing lots of third parties "testing" the waters again with token games, which again is not going to convince anyone of a real sea change here. We might get a single token Madden from EA, we might get NBA 2k17, we might get a bone thrown at us from others...
For all the excitement, I think there's a ton of inertia the Nintendo Switch will struggle against with third-parties entrenched into a mindset that ignores the Nintendo ecosystem. This will probably be especially prevalent in the mega-budget/super-premiere parts of the industry where companies are making huge bets years ahead of time and can't afford to get distracted by yet another platform as they near the finish line.
And of course, there's the question of whether Nintendo can create a platform where third parties can sell games, or at least certain types of games, or where third parties can find a non-risky way to survive. A major part of changing this issue will probably be just Nintendo trying to create as much of a Switch userbase as possible, building as much of a foundation for the platform, and pricing the hardware correctly in the market to create both demand and accessibility.
However, I DO think things are getting better. Launch is always exciting, modern game engines will make a significant difference, the hardware's concept could very well prove a strong lure, and hopefully indies are as excited about the platform as we are!
I think the most tantalizing hope, which may or may not prove true, is that the handheld world of developers comes to the Switch. This is sort of what's left of the mid-tier third party segment, and also part of what's left of the niche Japanese third party devs segment (that said, also some of the PS4 segment really). It'd be great if all the projects that drove passion for the PSVita and the Nintendo 3DS came to the switch without reserve in the future. And it'd be great if the titans of this segment also made the switch their new home.
I, for one, will be extremely excited if they announce Monster Hunter for the Switch. That game has a very significant following, and it's amazingly proven the ability to move its fanbase from the Sony ecosystem to the Nintendo 3DS.
I'm also very excited to hear that Dragon Quest XI is coming to the Switch! That's a pretty big vote of confidence from Square Enix and a major public signaling to consumers that they can expect Japan's premier RPG on the Nintendo system.
Ultimately, I think we'll see real progress here, true progress, but also slow progress with lots of inertia to overcome and the ball in Nintendo's court to prove that a game-hungry, game-buying userbase for third parties exist. I'm basically expecting things to get better... but at a rate that might get Nintendo back to equity, assuming everything continues going well, over the course of six years, not two.
