Native 2D graphics animation anytime soon?

So…

Has anyone heard any rumors regarding how soon Unity might come up with some native 2D graphics/sprite animation capabilities.

I am coding some buttons right now I would LOVE for them to suddenly animate into something else upon pressing them… like a plant animating into a bloom. As of right now I just have an on or off image for them per Unity GUI defaults.

Thanks.

2D Sprite and Animation should be coming in a 3.X (not 3.0) release. If you need something know, there is EX GUI and SpriteManager 2.
