I am usually against toylines pumping out cheap repaints as they are lazy cash grabs, but I am actually hoping Wicked Cool Toys/Jazwares does repaints in the "Halo" line as almost all of the Covenant troop types have multiple colorways while still having the same digital model.
Grunts traditionally come in orange (which we got in the 2pk with the Marine), red (shown as a prototype at the 2020 Toy Fair), blue (coming in wave 2) and yellow.
Elites usually pop up in yellow/gold (like we got in the Ghost set, Amazon 3pk and the upcoming wave 2 release), red, blue and purple.
Jackals usually have armor in blue (like the single figure), red and grey (shown as a prototype at the 2020 Toy Fair).
Brutes have gold (Chieftain like in the 2pk with MC), red (single pack Captain), blue and grey.
There may be other colors that I am missing, but you can see where I am going with this. They can use a slot in each wave for a Covenant troop recolor (hopefully with a different weapon each time) and I will not complain. They can use the money saved on tooling to expand the range with other Covenant troop types like Drones that usually only show up in 1 color or for individual characters like the Arbiter.
