Marvel has New Avengers # 16, with the whole-sale slaughter of Alpha Flight and Mailman Mike given the "Guardian" suit.

Marvel has "Heather" blasting the brains out of her cousins (volume 4) and "Mac", Aurora, Judd, and Snowbird (!) robbing a bank.

Marvel now has Carol Danvers leading Alpha Flight...
Personally I don't have a problem with any of this.
I much prefer it to Volume 3 and a lot of Mantlo's stuff.

It seems to me, and I may be wrong, that Alpha Flight is already gone.
Again, personally I'd say that the team is the most alive and prominent than it's been in decades.
I may be in the minority on that though.
