There was a live Rift interview with Scott Hartsman just now. Some juicy bits:
A potential zone with all PvP all the time is something they'll consider.
Dual targeting potentially in the future
The Port Scion zone with be 20 vs 20
On DPS meters. He stressed that a large number of people find them a horrible addition to MMO's and they are incredibly decisive.
Player housing maybe someday but that it takes away from a social atmosphere when people are always inside their homes playing house.
Cloaks: High on the consideration list.
Server names: The final list is being reorganized, names being removed/added. It *should* be available on the 22nd, 2 days before prelaunch.
