Think Nintendo "won" for me this year too.
Both Sony/MS didn't feel to announce much new, only more info/footages of games past announced, which I am still excited for, but was disappointed by the lack of new announcements. Sony did announce a bunch of VR stuff, but not massively interested, the main thing from Sony was Shadow of the Colossus for me.
Nintendo announced Metroid Prime 4 and at that moment I knew they won, ha ha. Then they announced Metroid 2 remake for 3DS. Mario + Luigi RPG stuff for 3DS. Yoshi Switch (Which I'm quite interested in), Kirby Switch (I'm not very interested in), Pokemon RPG Switch in development and Zelda DLC stuff.
Along with confirmation games I feared would be delayed are still on track for this year, though Xenoblade 2 is still Winter 2017, which is still a little vague and could still slip, we'll see.
And they somehow got me to care about 3DS stuff again, though... I still want full attention on Switch stuff after this last wave of 3DS stuff.
And of course stuff they shown from games previously announced has me hyped, pretty much all they shown I'm interested in, except Kirby/Skyrim really..., which Sony's did too admittedly, but I felt on Sony's side at least, not enough was shown for some of the stuff. Wanted to see way more god of war, but with Days Gone they shown enough to have me excited for it now, while before I simply didn't know/see enough to have me interested.
So yeah good job Nintendo, though the bigggggessssttt problem, no SSB Switch announcement. I really am dying to have Smash on Switch already, looking less likely it'll be this year

. If they are planning on porting Smash 4, they better have added new characters/stages/etc. to justify the longer wait!
