To be fair, if what's in the article is any indication, there will be a small set of broad terrain abilities rather than specific ones for specific models.
The terrain abilities included there are Cover (which will presumably be a bonus to save, or a penalty to attack rolls vs a unit in cover), Unstable (presumably a 'you can't have a unit sitting on top of this' rule), Obscuring (which will likely be a rule for LOS blocking or the like), and Place of Power. The latter's the only obvious place thus far for weird and specific rules to go, and I wonder if it'll be more like a simplified version of the Mystic Terrain rules/table of times latter rather than anything else.
