Will the interfaces likely continue to be POS OC-3 ? What is the growing
path for this: POS OC-12, GigE ?

The GSR line-cards to what you want would need to be the "edge" ones, based
on either Engine 3 or Engine 4+.
7600 requires WAN cards to support POS, I think GSR and Juniper M are more
likely candidates for this design.
