They are many new 2007.0 profiles which aren't listed in ${PORTDIR}/profiles/profiles.desc. It cause that `eselect profile list` don't display them. For example: default-linux/x86/2007.0 default-linux/x86/2007.0/desktop default-linux/amd64/2007.0
There are many people who don't get what's release about. They will be added once 2007.0 has been released, ktnx.
It seems that this bug was fixed long time ago.
