Something like:

# export DISTDIR=$(emerge --info | sed -n 's/^DISTDIR="\(.*\)"$/\1/p')
# emerge --fetchonly --pretend --quiet -u world | \
        grep -v "^$" | \
        while read SRC_URI; do \
                filename=`basename "${SRC_URI}"`; \
                [ ! -f "${DISTDIR}/${filename}" ] && \
                        echo "${SRC_URI}"; \
        done
