John Hight, who serves as Production Director on Diablo 3, says the most exciting thing about the PS4, in Blizzard's eyes, is the controller. "This is not a mouse, this is something different for us," Blizzard Senior System Designer Jason Bender says of the DualShock 4. "Working on a console version of Diablo 3, for us that means the controller is king," Lead Console Designer Josh Mosqueira adds.
The use of both analog sticks comes from a perceived player expectation on Blizzard's part – players will just expect to be able to do that with a console controller, Mosqueira says. The console versions of Diablo 3 on PS3 and PS4 will feature an evasion roll technique not available on PC.
The trackpad is demonstrated in the video above, sorting through a player's inventory in the new radial-style interface. "We really built our inventory screens and the UI system from the ground up," says Mosqueira. Another new ability is quick equip – at any time, players can press up on the dpad to cycle through the last few acquired items and equip any of them.
