Damn it, missed Fantasy Life. That's one game I will definitely be checking out when it launches here.

Looking forward to Swords and Soldiers II. The original wasn't bad, but it needed more depth.

Do we have a schedule on what is shown and when?

S&SII looks good visually, hopefully it's longer than the original.

Yup S&SII now.

Good to see the third party represent, but I'd like to see more of the "big" games.

Since 2012, when they opened a new North American branch to do just that.

I have no idea what's being announced or shown today but I know the Treehouse event goes on from now to 6PM Pacific Time (PDT) and I think an unannounced 3DS game will be shown at 6PM to 7:30PM PDT.

I doubt where getting major announcements today at Treehouse but don't take my word for it! Here's Nintendo description of the TreeHouse from the Nintendoeverything website: 

"Nintendo Treehouse: Live @ E3 is a new way to bring Nintendo fans closer to E3 than ever before. During all hours of E3 – which runs from June 10 to June 12 – members of the Treehouse, Nintendo of America’s Product Development division, will be live-streaming a wide variety of game demos directly from the show floor. Fans will be getting an unprecedented look at all the E3 games Nintendo has to offer. Instead of reading a short tweet or catching a gameplay trailer, fans can watch live as members of the Treehouse give in-depth gameplay demos of new and previously unannounced titles. There will also be special guest appearances from developers who will provide in-depth game commentary, including an appearance by Shigeru Miyamoto on the afternoon of Tuesday, June 10th. Keep your browser open to Twitch.tv/Nintendo beginning June 10th to make sure you don’t miss a minute of Nintendo Treehouse: Live @ E3, and follow @NintendoAmerica on Twitter for announcements about special guests, programming schedules and live updates."

Sounds like someone else agrees that this "mystery game" will be Majora's Mask, and that Zelda leaked/ruined that surprise yesterday.

I'll can imagine that today's 3DS game is going to be a real first look at the Pikachu Detective game.
I don't know if it counts as a new announcement or not.

That's my guess as well
