CCNP SP certification

I'm starting to study for the CCNP SP, I'll start with the SPROUTE exam. My question to this forum is more about the CCNP SP cert itself, why is it not much information about it in this forum? seems that people is not interested in pursuing this certification track?
any thoughs?

Most people go for the CCIE SP as its 2 exams (and hard exams at that) the move from CCNA SP to CCNP SP is very expensive and the amount of material available is very small compared to the CCIE SP.
Also Cisco does not seem to really care about the SP side of things, most ISP`s would receive in house training on things like MPLS,BGP etc.... From Cisco rather than pursue the cert itself.
And lastly back to the exams being expensive to complete ccna and ccnp SP is going to cost about 1800USD
