Q:
Previous year's rewards?
I doubt Mad Memoires will make a comeback since the story is about prince Eddy now, no clue as for the titles.
I wouldn’t worry about the armour, the whole set from last year was aestetically just reused exotic/PvP ( See http://wiki.guildwars2.com/wiki/Mad_King%27s_armor#Skin )
My quest is to find the dorito.
