Questions about party size and inventory. PArty size has been finalized yet, but probably similar to Diablo 2. 4-5 is about what Jay feels is prime.
Inventory is different, improvements for trading and exchanges. No finalized size though.
Another question about the gaming audience and attracting Diablo 2 characters and something about WoW, not really that important. :P
Question about classes and carrying over Diablo 2 ones. Jay says they're going to try and start fresh, maybe bring back some of them, it's not a goal to bring them all back.
Question asked about different energies for different classes, and they're going to explore this but no set plans as of yet.
