I wonder if the next revision of the iBooks and eMacs might give us some hint at when Tiger is going to be released. If the next revision is soon and only includes a small processor speed bump maybe larger hard drives, might that indicate Tiger would be coming early summer next year as that would give Apple time to include another revision/upgrade with better graphics card and maybe Tiger pre-installed in early summer? On the other hand if we see really major upgrades to the graphics cards/processor this year - maybe Tiger could be here early next year. What do you think?
