Don't forget the pretty decent lineup of She-Hulk, She-Thing, Crystal, and the often-overlooked E Spider-Man from "Mutant Mayhem". And the Power Pack is never hurt by packing a 19 DV either, if you're trying to keep things Modern Age.

It looks like the word is up on heroclix.com. Wildcards will be able to use ATAs again.

yep

Alternate Team Abilities: Alternate Team Abilities are now considered a different thing from Feat cards. ATAs are a part of the Modern Age of game play, though there are some differences from when they were considered Feats. Mechanically, ATAs will no longer replace existing team abilities – they will be additional abilities that the qualifying characters can use. As we started with Hammer of Thor, ATAs will be keyword driven rather than based on team symbols. What’s more, we will be going back through all of the existing ATAs and over the course of the next few months, making them available through print-and-play with revised, keyword-driven, additive mechanics. All of this requires some slight changes in order to balance things out a bit. As you’d expect, these pre-existing ATAs will be modified so that they cost a little bit more than they did before. Another balance will be that a force can only have one ATA assigned to it. Finally, wild cards will be allowed to use these team abilities, just like they can use any other team ability on your force.

Dang. If they keep the FF ATA similar but keyword-based, that brings SI Spider-Man and AV Black Panther, two of my favorite figures, into the Modern Age Fantastic Four Family.

But I strongly doubt this ATA will keep its 0 point cost.
