I don't think we have IPv6 yet but most likely we will have it in the next blueprint revision.
But Rick Mur who attended the CCIE SP Techtorial says that IPv6 is already there:

It would be nice to have a clarification.

hi
off topic : do we have IPv6 on CCIE SP ? the blueprint says nothing about IPv6 or 6VPE
