Hey I will need a new laptop by September. Im in between 13" and 15" MBP. I am in a dilema if i should buy in September or wait for the refresh wich would come on December or January since the C2D on 13" will be EOL'd. Do you think the MBP 15" will get updated along with the 13" and will they get Sandy Bridge by that time or will they just stick with higher clocked Arrandales?
