Privateer Press has posted a PDF with the new Mercenary Contracts for Warmachine MkII. They, in general, look pretty cool.
The Four Star Syndicate didn't see any real changes, which is fine, it was pretty straight forward anyways.
The Highborn Covenent got much better, simply by adding a unit Gun Mages or Long Gunners, both of which can take attachments. You can now paint up those Order of the Rose Lael Gun Mages you always wanted to do. Sweet!
The Seaforge keeps the same goodies, but instead of advance deploy, they get an extra 4" on the deployment zone. That should help with the general movement/mobility issues for those stunty legged folks.
Talon Charter - Didn't see any big changes here.
Magnus' Agenda gets moved from a Contract to a 'Theme Army' that has a bunch of bonuses, depending on how thematic you get with your choices. Neat things like Mag's Jacks can start with upkeep spells running in advance of the game or units getting pathfinder for the first turn. Pretty nifty stuff.
Makes me miss my merc already since I'm running Khador for the slow grow league.
one if by land, two if by sea
