Since a Walmart Avengers wave 2 is looking like a no go, I've come up with an idea of how we, the collectors, can still manage to get Iron Man Mark VII and Black Widow, and possibly a sleeveless Thor. It's pretty simple: Iron Man 3 is approaching. In the movie, I hope to and probably will see him in the Mark VII before the Mark VIII. The only way that won't happen is if they did what happened in Iron Man 2; give Tony a new armor from the start(Mark IV). But, as you can see here from this picture:
It's lookin like there won't be a new armor between the Mark VII and the armor shown at Comic Con. I realize, this can be changed, but let's hope it doesn't. So, all Hasbro has to do then is release another Walmart eclusive Iron Man 6" line like there was for the first 2 movies. In the IM2 Line, there was the Mark IV, V, and VI. So I'd say it's very possible we may finally get a Mark VII as long as they release another Walmart exc wave.
For Black Widow: Now, Black Widow has been assumed to appear in a movie before Avengers 2 based on an interview with Kevin Feige(film producr for Marvel). It's been confirmed that it won't be Iron Man 3, but, there will be a S.H.I.E.L.D. TV show as well. So, figures from the show may be possible, and Black Widow may be one of them. A figure of her from whatever movie she appears in(if she does so) is also possible as long as a 6" line is made for it(which it probably will be because Hasbro has made one for Iron Man, Iron Man 2, Thor, and Captain America). If a figure of her doesn't show up by the time her cameo does and/or by the time S.H.I.E.L.D. is on TV, then I'd bet on an Avengers 2 figure of her. And if Hasbro again skips out on the opportunity to make her, then that just makes no sense at all to me and I won't be a very happy camper.
And finally, Thor. Now he's the one I think is least likely to see. The hope for him is if in Thor 2, he again appears in his casual attire(he also could not, but it'd be more likely to see a figure of him like that if he does). Or, again Avengers 2 line. The one thing that keeps me hopeful is this picture of 6" Thor(already made) who I suppose Hasbro was going to include in the Avengers line, but for some reason decided against it.
So, there's my 2 cents. Hopefully we see AT LEAST Tony and Natasha pop up, but I'd love to see a Thor that is more screen accurate in some way to the Avengers version. The only other way we'd possibly see these figures is if Hasbro makes some out of the blue call to make a wave 2, but that seems like nothing but a pipe dream. I want Iron Man Mark VII, Black Widow, and a more screen accurate Thor so bad to complete my Avengers figures(posed in the poses of the circle scene) that I at one time considered to create an online petition(just a friendly one requesting to make the figures and a list of names who support the idea) and send it to Hasbro. I now realize that it's probably too late for that and it's also a pretty big dream as well. So, it's definitely possible to make the first two, the third is a bit of a stretch, but you never know. Fingers crossed!
