I will be the first to admit that I don't yet follow the game, but when a rumor comes across my desk, I might as well let others know what it is.
Of course this could all be a trick by a smart reader to get me interested and into the game. After all Privateer Press is not too far away, and I spent the last hour or so reading up on the game because of the email.
Just remember that this is a rumor.

The new Warmahordes stuff is up on pp's site for exigence. At templecon it was spoiled by hungerford that the new circle caster Bradigus will have a limited battlegroup (to constructs) and the synergy spell (which is totally new to hordes!)
