Besides Gundam their is another old mech series called Macross and it has a new series called Macross Delta. Basically we have jets that transforms into mechs to face off originally with mech piloted by giants. Since the trailer has no dialogue I have no idea what the fighting is about this time so we will have to see but in the mean time check out the trailer that is bringing the hype.
