This is the kind of question would better be answered using a crystal ball ;-) Seriously, there is a lot of discussions on the future of MPLS and some people were suggesting that Provider Backbone Transport (PBT) could even replace MPLS. I personally think MPLS is there for a while. I also believe that technologies such and PBT and others will be used as a complement to MPLS.

Yeah I am also looking for T-MPLS. As said by devang can you put a brief of the topics and let us know how cisco is going to add up in the roadmap. I know about CRS and giving GMPLS feature kindly correct if I am wrong.
As devang wrote if possible kindly share any good docs or links which can cleary out G-MPLS & T-MPLS concept.
I made a mistake when referring to MPLS-T. MPLS-T was put forward in ITU and went nowhere. What I actually meant was MPLS-TP (MPLS Transport Profile), which replaced MPLS-T (sometimes also called T-MPLS).
With MPLS-TP , you might get end to end MPLS i.e. from one CPE to other CPE over MPLS .
So you use MPLS as Access/Distribution layer and then take it that throgh IP/MPLS core. The best part is it will allow to full OAM capability and you may not required to run control plane on those access layer devices but you just configure static LSP through central NMS.
