Not to mention Whirlwind Hyperioses(plural?), Ork Flak-trucks and Tau skyrays.
At the moment, the only armies that lack Str 7+ AA systems are Necrons (outside apocalypse), Nids, Chaos and Eldar (all kinds).
Of those, there are fluff reasons for DE and Nids not to have any AAA while Eldar have both interceptor aircraft and light AAA (good against old style flyers, currently rubbish against the new uberflyers)
Really, the surprise is the lack of AAA for CSM, even from forgeworld (although they do have a pretty good fighter aircraft)
