I have decided to replace my pc setup with a 17" 2.5GHz Hi Res MBP and a 23" display. I know there have been rumblings for both of these to be updated. It isn't the end of the world for me if I don't get them right away. What are the chances that one or both of these will see significant updates in the near future (in the next 3 months)? Should I hold off, or will changes likely be little more than cosmetic?
