Not really 2019 is only the third year and the previous two years would be covered, the 3rd year of a console is often one of the most crucial as it's normally when things start to take off for the library, those 3 IPs would be needed then because that would either be when PS4 and X1 are in full swing or when their successors are being readied.

Take into account the combined portable and home console output, the's no need to rush them out as now the would be IPs like Pokemon, Fire Emblem, AC and some third party titles like Monster Hunter filling gaps and these are big sellers in themselves and that's before we come to possible titles like Metroid, Mario RPGs and all. If the speculation is true about SE the would also be DQXI, FFXIV and so on in 2017.

The's no need for the 3 IPs to be rushed out for 2018 if NX is a hybrid in some form that shares a library as the dynamic would be different from any previous platform, all the big sellers would be under one library meaning more breathing room as well as allowing time to build on previous installments and get them right to run nicely both on portable and home.

Maybe Pikmin 4? For 2017 I could see Retro's game come out, maybe a Paper Mario ( Paper Mario U was rumored to be in development in May, but it probably got moved), Diddy Kong Racing 2... The possibilities are endless!

Definitely Pikmin 4, Retros game also, I also think that Diddy Kong Racing 2 is real thing...real question is when exactly Nintendo will release them, I think Zelda U port and 3D Mario are almost certain for NX launch.

I could see Retro's game come out in early 2017 and Diddy Kong Racing 2 in May ( very similar to how MK8 came out in May). Who knows though. There are many games we don't know about. Besides those mentioned, there might also be a Kirby game ( the last fully fledged console game came out 4 years ago), Next Level's game ( could be Luigi's Mansion 3 or maybe a new Punch-Out game)..

Not to mention games like Pokemon or Animal Crossing if NX is really unified platform..

I think its pretty stupid to release all 3 biggest multiplayer IPs in same year, Splatoon 2 end of 2017, Mario Kart end of 2018, Smash 2019. would be perfect IMO.

Why? they're big IPs and different types of multiplayer games from each other, one of the reasons Wii U had problems was because of how spaced out the big momentum IPs were, imo they'll need around 3 big momentum titles a year to balance out the lower amount of third party games. It would be better to have a set up similar to the following the following:

2017: Zelda U port, 3D Mario, 2D Mario for holidays as well as being a steady seller over time.
2018: Animal Crossing, social type game like Tomodachi Life, Fire Emblem, Pokemon.
2019: Splatoon, Mario Kart, Smash.
2020: Metroid, Xenoblade 3, Zelda NX

This helps establish and maintain momentum as their comptitors have the luxury of always having games like COD and AC each holiday and are guaranteed a GTA game, this is free momentum for their competitors as no first or second party effort is required. Nintendo can then fit filler titles and some gems in the months between these games like Pikmin, DK, Kirby, Paper Mario, Mario RPGs, any third party collaboration (Bayo 3 etc...) etc...

I think NX will launch in 2016. That yours 2018. looks pretty weak because they are all similar genre of games while 2019 very strong, no need for that, it's better you have every year equally strong.

Also there is no need to release 3D and 2D Mario in same year.

NX will launch in 2016 imo but that will be Q4 which makes 2017 it's first year, the sales of the games I put in 2018 also makes it a stronger year then the previous and likely stronger then 2019. Pokemon will sell 10m easy, AC will shift around 5-8m, Tomodachi type game could hit 3-4m while Fire Emblem won't set sales on fire but that could be a good 2m+ so you see it's far stronger then what you're giving it credit for.

2D Mario is a steady seller and adds to the library.
