I've been watching Battle 360 on the History Channel.  Follows the Enterprise during the war in the Pacific.  And of course like all grognards it's made me think about gaming these battles.  That being said my dream supplement for SF now is a Pacific War supplement.  Tons of planes and rules for bombing land and naval targets as well as AA stats for those ships.  IMHO a game like SF would be perfect for battles like the Coral Sea and Midway.  No surface actions, just tons of air to air and air to ship goodness.
