: Even if Catalog hadn't confirmed that the ODST divisions remain in the Marine
: Corps to the extent that confirmed their role within the service there's
: still vague indication that would let you know they're still kicking. The
: MJOLNIR Helljumper armor set in Halo 4 is an entirely different model to
: the one we saw prominently in Halo 3: ODST . I doubt Materials Group
: would bother upgrading this series just for the more nostalgic Spartans if
: the ODSTs as a whole were disbanded. The eggheads would have probably told
: all those bucketheads to stop being nerds and get some Air Assault or
: Soldier armor.

I don't take the Halo 4 armor seriously enough to infer bits of canon from it. Upgrading ODST armor for nostalgic Spartans may be a waste of resources, but there's redundant armor sets specialized in tracking enemies. Materials Group clearly has funding to spare.
