Welcome to Librarium Online!
I've gotten back into 40K after being gone a while and was looking through the IG codex.
I couldn't help but notice the griffen has gone missing. However I noticed it in the armor company PDF in the IG articles thread here. However it doesn't give the rules for the heavy morter(presumably the same) and seems to imply you can only take it if you're using an armored company.
Is this true? Is the griffen dead to vanilla IG armies?
Its still usable but they excluded it from the latest codex for space reasons. The Griffon isn't very popular as the Basilisk overshadows it. Imperial Armour has addressed the issue somewhat by giving the Griffon access to several variant shells with different effects that help a bit. However it and the Exterminator were omitted from the codex, though as you noted they rectified it by keeping the stats on GW's site.
