Just after writing the above post yesterday I did get some luck.
at TRU in Mishawaka, Indiana I grabbed: MJ, Iron Patriot and Winter Soldier (short hair). Someone beat me to the other 3 in that wave.
At Target I nabbed the Wolverine with the nice head sculpt. Also noticed that Walmart had them too.
But still, on a discouraging note - Target now has a full peg of the Silver/Red Iron Man, a full peg of House of M Spidey, and I think a full peg of Cap Americas. So I am not really thinking I will see anything new in a while. I do try and help the cause whenever I go there by moving some of the peg warmers to the end cap that has figures on it now - in hopes that some kids will have their parents impulse buy them.
