We've seen a lot of improvements to the inventory system over the years. We've seen bags get bigger, sorting and searching included, items like mounts, pets, toys and soon heirloom items all removed from our bags (along with quest items) to help make space. We've seen void storage, so that we can take items we want to keep but not necessarily need access to and put them somewhere, and many consumable items and various reagents have been improved to stack to higher amounts, freeing up more bag space.

This has me wondering, though, are we forever in a bag arms race between all the things we may want, and the amount of space we have? Will we eventually see consumables get their own tab, or reagents go from the various kinds of profession and reagent bags in the bank to a tab of their own? What changes do you foresee for our always filling bags?
