There will be a demo of Mario Maker one week after the E3? But only at best buy?

Nice! More TreeHouse!

That was great XD

Yes, all they said this was going to be was announcment of what they will be doing for E3. Kind of sad they didn't team up with anyone to make the annoucment but can not have everything you want.

Hilarious! XD

It's Nintendo after all :P THe championship pretty big announcement though.

The rest of the news will come at E3.

Updated OP and thread title.

Trailer was really awesome, but I thought they would tell us what they want to show at E3.

They have said "more games than the last year"

Last year they showed a good amount of games.

I loved the interventions from the developers, that´s coming again too.

Also treehouse is nice.

The Nintendo World Championship could be something big! It sounds exciting.
