Regardless of how lame and pathetic Harmony Gold is as an 'intellectual property owner'… you do have a point, and I try to make the same one often enough, that the Warhammer as it appears in the 'reboot' trailer really doesn't look nearly enough like the Macross Tomahawk, otherwise known as an Excaliber (not Excalibur, which would be the right spelling for the sword name) in Robotech.

Seriously, doing something like this is just invariably going to screw them back anyway- if they were smart, they'd show fans of the mecha genre in general that they aren't assholes and not raise such a stink. As it is, it's just making them even more shunned.
