In the most recent issue of Wizard, they have a small bit on Civil War. Here is a quote from the article:
"...the rift that divides Captain America and Iron Man forms after a massive tragedy involving Marvel heroes kills hundreds of innocent bystanders. As a result of this catastrophe, the government institutes a superhero registration program..."
I dunno about you guys, but the moment I read this, I immediately thought 'Alpha Flight!', especially considering that NA #16 is touted as a Prologue to Civil War, which this sounds like it'd be.
So, yeah, Alpha faces off against the Collective, hundreds die, Civil War starts? Sounds plausible?
