That is what I hear a lot of people saying (mainly people that are trying to fight buyers remorse for not being patient enough or absolutely needed a new computer right away). Of course the next update after the Penryn revision will be more significant, but there is a difference between waiting a month and waiting 8 months. This is how I see it. Current MBP vs. Penryn upgrade. +-5% speed increase between equally clocked processors. The new base model will likely start at 2.5GHz. That is already about a 18-20% boost SSE4 will supply a speed increase up to 40%, especially as time goes on. Also worth mentioning, 6mb L2, battery, and heat. (All for the same price as the current model.) I don't understand how people say this only a slight increase or a negligible update.
