vonHardenberg: The "unseen" Mechs are still pending, due to the lawsuit between those-who-shall-not-be-named and Piranha Interactive still running. Since the mech designs are based on the MWO ones and the lawsuit being bullshit as it is, there's a good chance that the ones that actually have an MWO redesigned model might make it in the game, such as the Marauder, Warhammer, Phoenix Hawk etc.
Adding them before this lawsuit bullshit is sorted out would just cause you-know-who to start suing again.
Besides, both Wasp and Stinger are low-tonnage junk in the vein of the Locust. They're like miniature pinschers and chihuahuas....they're nippy, funny, and they make those cute squelching sounds when you squash them underfoot.
Besides, screw the lore. I'm for whatever makes better gameplay at this moment, and also, playing giant robot limb removal pokémon ("Gotta Leg Them All!") is part of what keeps people going after the main story is over.
That lawsuit was "Dismissed with Prejudice" - as far as Harebrained and Weisman are concerned, anyway - as of 09 April, 2018, however it was filed against Harebrained over a claim that HBS'
Locust somehow resembled a
Marauder (aka Zentradi Officer's Pod), and not over HBS' direct use of the "Unseen" mechs.
The suit is still proceeding against Piranha, however, who did directly use the "Unseen" in MWO (and in their work-in-progress
MW5. PGI found some old court decisions that Harmony Gold doesn't actually own the copyrights to the "Unseen", so there's no telling where that might go and if it will set a precedent that will finally allow the use of those designs, but for now, given that HBS only got out of the suit precisely
because they weren't using any of those mechs.
