Tim -- I was messing around with sabre, and it seems like the first one will be on the DFW-NRT route, replacing an MD-11.

Depart DFW 1115A Arrive NRT 335P

And I think that the others will be on the other NRT routes (ORD, SJC) and on the DFW-KIX route. Hopefully they'll be on the South American routes in the next year, as I will be going to SSA (Salvador,Brazil) and will be on AA connecting to TAM probably in GRU.
