HP is putting out several new displays including the ZR24w and ZR22w, and they have just added the ZR30w.

This is a 30-inch monitor with four-way ergonomic support including height adjustment, swivel, tilt, and pivot. It also has an S-IPS panel, 3000:1 contrast ratio, DisplayPort, DVI port, integrated four-port USB hub, as well as 2,560 x 1,600 resolution.

My source does not have a price or availability date at this given time.
