So the Cauldron of Jordan and Nephalem Cube have been completely removed from the game [source]. Do you like this?
In case you don't know, these items were part of you inventory and allowed you to sell and salvage (i.e. disenchant) junk on the go, without having to return to Town every time your inventory was full. This was quite handy, but since they've now added a "Town Portal" button right on the interface, it will be very easy to just make a trip to Town and sell/salvage your junk there.
I personally like it. In D2 I always enjoyed making "junk-selling" trips to Town every now and then, which also served to check for upgrades, hand in quests, etc.
