What I read was that the stats weren't finalized. There was talk of modular weaponry, like I said. The Ion cannons of course will probably be similar to the Riptide, but with higher volume of shots. The SUPER guns are probably ordinance, but there are two shoulder mounts (that 3-piece gun uses both mounts and stretches across the back). There's talk of massive missile pods, AND an arm-mounted giant missile launcher as well.
Burst Cannons will probably be point defense, and smart missiles are smart missiles.
