I'd say that the huge address space makes life impossible for scanning worms.

That doesn't mean that there can be no successful scanning at all with IPv6, but it needs to be highly targeted if you want results the same year, so just pumping random numbers in the destination address field like SQL slammer did so successfully doesn't cut it in IPv6.
