AFAIK this reflects the reality very well. There are huge PBB 
deployments in very large networks but the overall number of networks, 
using PBB, is very low. Even in those networks PBB is/will be phased out 
so don't expect any new deployments. It is still well supported by the 
vendors who initially invested into PBB.
