This won't be under my tree for Christmas, as it's 500 bucks (sale price, goes to $600 in Jan.) but deserves to be mentioned because it's pretty much the end-all epic orchestral library. 240 players (!), 100 strings, 60 brass, 60 woodwind and 20 percussion. Holy crap. This would have been Beethoven's pipe dream (he rocked the world when he put 80 players on one stage).

Uh... wow.     Big is the first word that immediately comes to mind.   The second one is flexible.     Oh, and the third is playable.   
 
Anyone got $500 they don't need?
