There will be new MacBook Pros at some point in the near future – but I think Apple is less and less inclined to give any such “boring” changes their own events.

I think Apple has been moving away from situations where they are forced to present something – anything – (like Macworld) and will try to only use events for really new stuff. The two lone exceptions are the WWDC and the yearly iPod event. You might see simple spec changes in the WWDC keynote (probably only mentioned in passing), but I don’t think you will see them anywhere else.

(Design changes might be something they would present at such an event. But since we just lived through the change to the Unibody design I don’t think we will see changes in the next one to two years. That would be unnecessary and stupid.)
