Reading your list makes me realize how out of touch I am with Nintendo these days. I didn't even think of Xenoblade, Fire Emblem, Zelda DLC, Pikmin...
To be honest, if your prediction comes true it won't be a great conference...Retro's game better not be Donkey Kong in that case :p
This would kill everyone
Edit: By the way, has it been officially confirmed that the Spotlight is Switch only?
