A new Super Mario Galaxy game to make a trilogy?

Not only did we get spectacular news about a Wind Waker HD remake for the Wii U during the Wii U Direct broadcast today, we were also told that a new Super Mario title is currently in development for the console.

The Nintendo EAD Tokyo Software Development team behind the incredible Super Mario Galaxy titles for Wii and popular Super Mario 3D Land for 3DS are well underway working on Mario's upcoming 3D experience for the shiny new Wii U.

No further details on a launch date have been given, but the game is scheduled to be playable at this year's E3. We wonder what Nintendo has up its sleeves regarding a new Mario adventure. Super Mario Galaxy 3, perhaps? Or something completely original? Let us know what you think!
