Next Macbook update?

Any idea when the next Macbook update will be out? It looks like they just updated the Macbook Pros?

I'm still using an old iBook G4 and should probably upgrade one of these days. Though, it might be best to hold out for the next update if it's going to be within the next several months. Any chance? I'm sort of contemplating going for the Pro as it's only $200 more. The RAM upgrade alone on the Macbook would bring it within $100 of the Pro.

Don't care much for the aluminum case, though. I'm quite a fan of the classic white.



Also, any speculation on whether or not the current base Pro or any in-the-near-future base Macbook will be able to run Starcraft 2?
