I sure hope so, thats why I got one. I would think the A would be in pretty soon (for CIG standards anyway), since CIG said that the smaller the Hull series the faster it would get in engine.
That being said, the Hull series is probably not even on the backburner yet. It's a ship thats tailor made for the PU, and will just be more trouble than its worth for Arena Commander.
That being said there WILL be an LTI Reliant sale, and it has been stated that it will be fast tracked from Concept to Flight ready, so I would expect that to come along before the Hull A.
