Subject: LDP or RSVP??

It seems that LDP is suitable for hop-by-hop routed LSP
establishment, and CR-LDP or RSVP is suitable for
explicitly-routed LSPs. But RSVP seems capable of setting
up hop-by-hop routed LSPs too. From Cisco's web pages,
IOS adopts a LDP-like protocol, TDP, for hop-by-hop routed LSP
establishment now. I'm interested in which protocol Cisco will
adopt for explicitly-routed LSPs. Will Cisco adopt LDP+RSVP for
hop-by-hop and explicitly-routed LSPs? or only RSVP for both
kinds of LSPs? What's others' attitude to these two protocols?
Will it be the truth that finally every vendor has to implement both
protocols for interoperatability?
