"Old school Alpha Flight fans will be happy with Issue #1 because it actually concentrates on one of the original cast members and somebody else from Alpha Flight's past. So we want to give it a new launch without baggage, but the first issue is definitely dedicated to the roots of Alpha Flight."
When I first saw this and coupled with the initial speculation about Mac, I thought maybe Mac passing on the mantle to a previous member. However, now that we know the big reveal won't be until #3, I'm thinking a very battered and infirm Shaman passing on the mantle to Talisman. Theoretically if Michael can't carry on and given her origins, Elizabeth would be the obvious choice to become the next Sarcee Shaman.

Pure speculation of course.
