As ever, you can read all Rygarius' responses to player questions after the break -- there's a lot of great information on how they're categorizing toys before players get to weigh in with their feedback. It seems likely that Archaeology items will be included, for example, and equippable items with effects will likely be turned into a spell, allowing the player to use the effect without having to have the item equipped.
However, Rygarius does point out that certain items (the particular one under discussion being Sylvanas' Music Box) may remain character specific. Other things such as the Jade Raccoon are under consideration as toys, but not confirmed either way. Regardless, the goal is to free up more space in your inventory, something that will be welcomed by all!
