We know that there is an elf expansion in the works that will be released in due time.
What are your hopes for this expansion?
If the AGoT faction expansions are any clue, then the elf expansion should have:
-a price range of $25-30
-at least one non-quest card (see below) for each CS race...hopefully more heroes, since AGoT's Kings of the Sea got some kings thrown into the mix.
-some more race specific quests (trying to draw a parallel to AGoT's plot cards here)
-some neutral cards
-a multiplayer rule or draft variant
The card count can be anywhere from 60-120. If it follows the AGoT's distribution scheme, which I find highly unlikely, then it can be 60 cards (no duplication) + resin capital board just like the Kings of the Sea expansion or 120 cards (60 uniques duplicated once). The other alternative being simply half of Core set's 220 count. Personally, for the above stated price range, I hope there will be a unique happy medium for the companion set: somewhere around 90+ range with some duplication (I would prefer no duplication, but there is that CS precedent).
Speculations are welcome...
