i think were seeing a delay in merom because the macbook pro was slimed when core duo was pasted in with hopes of merom being cooler. now with merom slightly hotter than the already hot duo 1 apple is taking this into acccount for santarosa and taking it's time to release the merom upgrade so that there is less redesign at santarosa and to counter act any unexpected hotter chips. plus they are still learning from the paste incident. so no thinner MBP's for a while
