I don't think it's ever going to come out. Dilblo seems like he might never put this into a tenno gen, it's already been 2 years now,and I've seen other helms coming into the game for rhino that's been around for only a few months but this one has had no real movment besides a slight idea change of making two versions and Rhino's ver. would have one broken horn maybe? Otherwise, he has made Topic that seems like it put the last nail in the coffen for this helm.

So without it being suger coated, "The project is DEAD." If by some miracle this works out that would be cool and we can get a rather unique Helm for Rhino, but don't keep your hopes up. Now if I am wrong, (And I hope I am.) fill me in what's going on.
