According to gamesmark the big N needs some extra help with Super Smash bros revolution and they are hiring people to fill the following positions:

• Game Programmer
• 3D Character Designer/Modeler
• 3D Character Animator
• 3D Map Designer

If they are hiring now it´s not because they are just starting to work on the game as other webstites have stated, i think it is only to have some extra help to speed up the development proccess and have the game ready to be available on revolution´s launch day just as Iwata said on this year´s E3.
