sh*t I was planning on NOT buying a console this generation... Sony really upped their game though!
Nintendo may talk about pokemon - that's coming out this fall, yeah we already know about it, but I bet it comes up. And yeah there is a new zelda in development for 3DS as well as a remake of A Link To the Past also on 3DS as well as Majora's Mask remake for 3DS iirc
They already have a lot of their Nintendo/Supernintendo/N64 games on the eshop - not sure if wii u also gets gamecube games - but wii gets all the aforementioned and wii u does too.
3DS also has nintendo/gameboy/gameboy colour on the eshop. Ambassadors got some GBA games, but so far none have been for sale yet. They may announce GBA games coming to the 3DS.
(sure frigging hope so, I really want them on my bloody 3DS already)
TBH I think nintendo just better thank their lucky stars they have the best portable console out currently in this generation (technically speaking VITA is better but there still isn't a big enough library for it, and it is not at all cost competitive)
