I doubt they'd announce more than 2 big franchise games.

I hope Nintendo announes something interesting this time, last year they had all in their favour and they were terribly dissapointing. I guess they don't want to be criticised again so I'm expecting some info on the new SSB for WiiU and 3DS, and at least one out of: a Zelda game for 3DS (they've been talking about the LttP style game for too long now), and a big franchise game for WiiU but I can't really imagine which (doubt it would be a Zelda if they announce one for 3DS, a new Mario game might be too early considering they've already released 3 Mario games in the past 18 months, and a new MK game would be better off coming out well after the new SSB game since both games tend to attract the same players)... might be a lower tier franchise game like Metroid, Starfox, etc.

In the end they might just end up trolling us again, and only talk about Nintendo Land updates, new WiiU hardware, announce the SSB game we already know is coming anyway with a small trailer, and some remakes for 3DS. Nintendo seems to prefer making their important announcements in their own conferences rather than in E3.

multiple articles say that the three i mentioned are confirmed not rumored

Still haven't made a good starfox since 64. They should get on that.

They haven't made one since then period.
Always third party.
