Apple's annual developer conference in San Francisco.
New Santa Rosa MacBooks in Apple Stores [Confirmed]
13.3/2.2/2X512/120/SD - DL White
The specs are said to be as follows [Confirmed]:
$1099.00 2.0GHz/1GB RAM/80GB/Combo/GMA X3100
$1299.00 2.2GHz/1GB RAM//120GB/SD-DL/GMA X3100
$1499.00 2.2GHz/1GB RAM//160GB/SD-DL/GMA X3100
The 2.0/2.2GHz speeds do suggest that these MacBooks are based on the Santa Rosa chipset, and they reportedly do include the X3100 integrated graphics chip that had been spotted amongst Leopard's drivers. Note that Apple often sells slightly upgraded models in their retail stores so the 160GB models may be retail configurations.
We can only assume they will be officially announced next Tuesday.
Update: The Apple Store is now showing the new specs.
