The central region is for the moment more stable than expected, the big powers seem to have wars they prefer to fight before going for the isle (or I don't know for the others).

That is not so easy. I guess only R'lyeh can take it down easily without huge losses, monsters there really cannot deal with illithids and astral mages.
Other nations well... there is Ermor, Arcoscephale and who else around it? They do not want to take it with heavy losses. I guess everyone there is preparing for spring to take it just before first summer month to score that VP.
I agree. There's no point sacrificing an army to raid the island, as someone else would get to take it the turn after. Several armies attacking on the same turn would make interesting viewing on the battle replays though.
