There's an add on the back of Game Trade Magazine #138 for the Dead Marshes and it shows Boromir as a Tactics Hero.
Here's is stats if they haven't been spoiled already
Boromir - Tactics
THREAT - 11
WP - 1
ATTK - 3
DEF - 2
HP - 5
Action - Raise your threat by 1 to ready Boromir
Action - Discard Boromir to deal 2 damage to each enemy engaged with a single player.
The add also shows a Spirit Ally that appears to be an "Elfhelm..." something or another (blocked by Boromir's card.)
Cost - 4
WP - 1
ATTK - 2
DEF - 2
HP - 3
Response that has something to do with questing units and quest card effects (most of text is blocked).
A treachery card called "Through the Mist" with a When Revealed effect that calls for an "escape test" and looks like it might force discards or raise threat of a failed test (most of text is blocked by the "Elfhelm...") Also has the text "Escape 3" that somehow related to the "escape test?"
A neutral attachement called Song of Battle. Not text visible but sure its like Song of Kings for Tactics.
FYI,
