I definitely feel pretty lucky. Of my favourite bands, these 5 (along with Cannibal Corpse, whose I'm seeing in a couple months) are the only ones I haven't seen that are still touring. And to be fair, Manowar, Avantasia, and Sodom are near impossible to see in North America, so they'll probably be on there for a long time.
