Do we know for certain that it's a vertical line of hardpoints? I'd rather a diamond shaped fire pattern or something like that, mostly just for aesthetic reasons.
for certain, we only know that the top most slot is a large one, and that there is at least one medium one infront of it.
its very well possible that what i have marked as "medium" above the cockpit may be another large one or two mediums under one hatch (something FDEV has never done before except for the corvettes two huge)
