I think it's most important that they have 2 heavy hitters each year (this year they had to me 3 1/2, BOTW, Splatoon 2, and Odyssey. Threw in the half because Mario Kart was a port). Pokémon is one of those for next year potentially, but I'm wondering if they're gonna try to give Metroid Prime 4 the same treatment, seeing the outcry from the fans even though it hasn't really ever sold fantastic numbers.

Either way, they still have at least 5 or 6 heavy hitters left, and that does not include potential Zelda and Odyssey sequels.

Not much love for Donkey Kong?

Seems like a decent chance with no big 2D platformer on the system yet.
And I know people who won't even think about getting a Nintendo console until a Donkey Kong game is out.

Fire Emblem will probably still sell pretty well, even if its so-called Waifu Emblem. The games are well received and were able to allow new players or timid players to learn about the game without too much punishment.

And I doubt a price cut will happen next Spring. Maybe Holiday 2018, but we're looking at a system that's selling pretty well and Nintendo is making sure they get as much out of the system sales-wise at its current price. Its still hard to analyze how much demand is there for Switch, but if there is still a great deal of demand, I doubt we'll see a price cut in 2018.

I think some people took this question differently. I answered how I thought it would be alright for the company while I think many people answered how many would be best personally.

I'd say 4 major (semi-)exclusives, one per quarter like 2017: Breath of the Wild, Mario Kart 8 Deluxe, Splatoon 2 and Super Mario Odyssey. 3 is OK, but that's the minimum. Games like Pokémon, Super Smash Bros., Animal Crossing, 2D Super Mario, 2D Zelda, Donkey Kong Country and strong new ips. Maybe Mario Party too, if it can reach MP Wii / DS numbers.

With 6-8 games that are not best-sellers (1-2-Switch, ARMS, Mario+Rabbids: Kingdom Battle, Pokkén Tournament DX, Fire Emblem Warriors, Snipperclips and Xenoblade Chronicles 2 for 2017).

If anyone has the franchises to do it, Nintendo has. At least 7 or 8 big hitter franchises. A few more with the potential to become so. Plus there could be more collaborations and new IP's. Also, love the earlier comment about "Switch Sports". Hardly been mentioned anywhere but that thing could be massive!

All in all, big or small, Nintendo has nearly 50 franchises!

Two a year

Switch now has popularity and is successful. No need to pump out insane amounts of games unless Nintendo feels like breaking records

The Switch is riding on a different kind of hype.  It is fun to have the flexibilitiy it provides.  The joycons, the portable, the small size, etc.  It is really "play your way" and it works.  It can get ports all day long and still sell above expectations.  The question isn't how many exclusives, but what type of exclusives does it need and how many games of each genre does it need to keep momentum (exclusive or not).

Really depends on what you call major..

If you are talking about big budget games, then 3-4 a year is good enough, one for each quarter
