So for me only.... technically, I couldn't call them AUS price variants as the actual issue is in US dollars, covered with what I would agree with you an official AUS price sticker. That said, knowing those are out there and/or until an XForce 2 or 3 shows up with an AUS price point, I would still include them in my own personal collection as AUS variants. Like i said, with an ** .
I'm sure the folks at Grand Comics Database would agree with us from a technical standpoint as well.
And it's all for fun anyway.
