Let's see...
October:
Mario 3D (Hopefully Galaxy 3);
Zelda U porting;
Pokken Porting;
Nintendoland Like game showing off new gimmiks;
New IP.
November:
Animal Crossing NX;
Smash 4 Premium Edition;
December:
Mother 4 (making impossible calls over here but I neded a HUGE game for Christmas :v)
January:
Metroid NX
February:
Kid Icarus NX (best gift ever for S.Valentine)
March:
Xenoblade spin-off cuz Nintendo
June:
Codename S.T.E.A.M. sequel, possibly with different graphics because that was the problem with the game...
F-Zero NX announcement at E3 releas date TBD (I know it isn't a release but with all these big names in the first year people would be upset if I didn't name F-Zero)
August:
Splatoon 2
September:
Kirby NX (special game in memory of Mr. Iwata)
So this is how you build a good instal base imho, keep in mind that if Nintendo follows this list NX will sell so much that they won't even have the problem of having used most of the main IPs in the first year
