Besides the obvious items speculate on some items you would like to see making it to the toybox; or perhaps items that will go in if you have them before the patch but may be unobtainable afterwards. I've seen plenty of people wanting vargoths staff, the water sprayer from several quests, and toy trinkets (orb of deception for example).
For me I'm hoping the sun lute and arcanite ripper make it into the toybox along with fandrals staff effect or the flame cat seeds.
