Here is some other news!

Fantasy Life for 3DS announced for western release

In Mario Party 10, all of the players will ride in a kart like in Mario Party 9. A 5th player can use the gamepad to control Bowser in minigames, with the goal being to make all of the other players lose. It has been stated that Bowser will take a central role in Mario Party 10.

In Smash Brothers, Amiibo will be used to create a computer controlled version of each individual fighter that will grow stronger and use new moves as it fights, levels up, and gains increased stats. Each Amiibo fighter will be different because of these attributes. Players can fight against or alongside their Amiibo, as well as pit two of them against each other to battle.

Mii's are in the new Smash Brothers. Come in 3 varieties.

Palutena is playable in the new Smash Brothers

Great list.

Thank you . I'll edit it and add some more stuff.

Nice, I hadn't seen the Mario vs Donkey Kong news. I'm always happy for more of that.

@Jargon

Yeah its the maRio dk gameplay I've missed.

Rainbow Curse is for Wii U bro!

Maaaan I want like all of these games.

Thanks for putting this together.

Mario Party 10's hook looks really amusing. Having Bowser trying to mess everything up is a cool way to have a fifth player and make use of the Wii U's Gamepad.

Seeing so much of Nintendo's E3 news complied is awesome. There's a lot to look forward to.

Thanks for putting this together.

I love One-Stop shopping. :)

Yeah I want to see how MP10 deals with Bowser if you only have two players. A little bummed to see the "all in one car" mechanic come back, but I have to admit it made the games much shorter. Just didn't like the lack of strategy it introduced on the board.

So far, super pumped for:

Layton vs. Ace Attorney
Mario Party 10 - Looks like some more of the same as MP9 but I liked what I played of that. Any party game I can play with Amanda gets a thumbs up.
Yoshi's Wooly World - Way more interested in this than Yoshi's Epic Yarn.
Super Smash Bros. for Wii U (is this going to be the final name or what?)
Xenoblade Chronicles X (can't wait)
Zelda (I want answers - what's up with the main character? Is it Link? Is it a girl? What's going on??)

Less excited/on the fence about:
Amiibo - One the one hand, I like this better than DLC - it's kind of like a key (so maybe we wouldn't have to pay for DLC per game). What happens if you put Link on the Gamepad when you're playing Mario Kart?? I have to see it in action. So far, not interested with what it does in Smash.
Captain Toad - I think Amanda is more excited about this than me. I liked the Captain Toad stuff, but I don't know if I liked it enough to buy a full game.
Mario Maker - I WANT to be SUPER excited about this but I'm afraid it's going to be way more limiting than I'm hoping for. I really hope it lets us use different graphical styles, music, maybe a world map editor, etc. I really would want them to go ALL out on this. It'd be cool if there was a small downloadable game on 3DS that could download these levels as well. Just a small game that could latch onto the 'hooks' of the Wii U version.

Mario Party 9 and 3DS are big disappointments to me, so I'm not happy they're continuing on that path. Boo to mini stars and no mimi games every round. I do like that 5 player will be featured though.

Mario Party 10 was the highlight of the show for me.
