On step 11 of the Macbook it is mentioned:
"All three antenna cables appear to route into the display assembly. This may be an improvement for Bluetooth range, since on previous MacBooks the Bluetooth antenna was located above the optical drive and not inside the display assembly."
Is this new antenna on MBP connected to the same port (J?) on the Airport board than the one routed into the display assembly above mentioned? It seams that this antenna is being used for bluetooth only and the other two remaining for WiFi (2,4 and 5 Ghz). Is that correct? If so, there will not be any WiFi radio performance improvement compared to previous MBP.
