The Mechromancer was announced awhile back as the fifth playable character in Borderlands 2. She is now available on the Xbox 360, PlayStation 3, and PC for download. If you didn’t pre-order the game, the content will cost you $10 or 800MSP.
More information on the Mechromancer can be found here. Below is an image of Gaige’s skill tree:
