Will Games Workshop be bringing out a model of the Mumakil (those big, huge eliphant things). If so when will they be released and how much will they cost?
I doubt if they will coz it would be a "mammoth" (bad pun I know) task to make them

Yes they will, it will come out with the Haradrim with the Pellenor Fields Supplement in July.
Imrahil and the Knights of Dol-Amroth with be out as well.

ya i heard when i got some elves and gandelf on shadowfax they say its gonna be bigger than the balrog i say about 5 times as big with archers 20 wounds (at least) archers on top 3 attack 10 deffence basicly this thing could kill most of my high elf force(56 plus gil-galad eowyn on horseback and gandelf on shadowfax) i estemate upwards on 400 points at a guess 1000 thats the most points for anything but im probably wrong
