I don't see how anyone could have a problem with Wolverine appearing in AF. One, it has always been said that he was meant to lead them, and two, Wolverine sells.
I would've loved to see a new team formed, at least for a time, around Wolverine. And speaking of Wolverine, has the death of AF been on his mind *at all* since the Collective arc?
As for the Hulk not coming to Canada in the World War Hulk crossover; the really real reason is that his run ins with Wolverine and Sasquatch have in fact taught him better than to drop the gloves with us Canucks.
