Famous Weapons Lore

So we now know that Weapon Foundries are coming into Destiny, what other Manufacturers could make an appearance in Destiny? _____ [spoiler]We know Suros from the infamous [b]Suros Regime[/b], recently matched [b]Hardlight[/b] to the Omolon foundry, and uncovered a new manufacturer called Hakke which we have no relation to pre TTK. I know these aren't the only three weapon manufacturers in Destiny. I could only find one other in the grimoire: Crux/Lomar. Two specialized engineers who are responsible for the [b]Truth[/b] and [b]Dragon's Breath[/b] rocket launchers. Leaving me to believe if they do make it back into Destiny they will be producing explosive weapons that continuously push the limits of technological achievement. One last thing I would like to share is [b]Icebreaker[/b] was a prototype series of sniper rifles made by multiple weapon manufacturers working together; later canceled after its first field test once it was discovered to be quite lethal to its wielder.[/spoiler]
