After its debut at the Four Horsemen event in February, people have been asking "So when is this Mythic Legions thing happening?" MythicLegions.com is live right now with a page featuring 13 named characters - this is news!
No release dates, pricing, or other specifics are known - but it's progress. I expect something in early 2015. As always, we'll throw up a notice somewhere as soon as any way to get these is announced somewhere.
