The one preorder bonus, the Requiem Pack, got released some time after:
H2016 release: March 11th 2016
Requiem Pack release: Jan 31st 2017
H2 had no preorder bonus in that way, but the collectors items were given to Gold users as well despite not intended at release time.
H2 release: Nov 13th 2018
Collector’s Pack addition to Gold: Jan 9th 2019
I would expect the Trinity Pack to be released around a year later if not less, but that won’t be advertised prior so no guarantee.
