The meeting will probably be mainly about the account system and first Mobile games, which seem to get investors pulses to quicken.
Nothing on the NX and if someone brings it up there will be the customary "we plan to talk about that at a later date". Because if one thing if they say they are going to talk about something in 2016 it will be in 2016 for better or worse. If they talk about anything they will talk about the QoL platform that is coming out because they paid quite a bit of money for it.
There will be a ton of amiibo talk since that is what Nintendo is making money from and that is what investors want to hear about - The things that make money currently and how they will build on that success.
And just maybe we will hear a bit more on LoZ or a "surprise" announcment for a game that will not release until the middle of 2016 or the end.
We may hear about the shipment number of FE:Fate since it is happening now. And maybe initial digital sales, IF the game is doing well.
