Halo skins I did not activate/claim

So I missed a few previous seasonal skins from the past of the weekly rotation. one example is the black rhine skin for the halo 3 tank…any chance these weekly or seasonal skins will come back in the future?

Reviewing it I see the Halo 3 Scorpion skin Black Rhine has only been featured twice. First in its initial season (Season 6) and once again the following season (Season 7).

While it’s only appeared twice, the fact that it’s appeared again outside its initial season is a good sign it will appear again.
