Acer is to bring the Predator XR342CKP to the market, in fact already has done so silently. The unit is an update of the Predator XR342CK  and provides a 100Hz native refresh rate (75Hz on the old model). 

The XR Series monitors combine the latest color technology and performance with a gaming style design. The specs are online with the previous P model including an ultra wide panel at a 3440x1440 resolution (IPS panel). The monitor supports AMD FreeSync for variable refresh rates, a contrast ratio of 1000: 1, 300 cd/m2 brightness, 172/178 viewing angles, 1.07b color depth, and the standard sRGB color gamut. The listed 100 Hz is tagged as overclocked frequency.

The XR342CKP is on the Acer website with a suggested retail price of 1799 USD.

Update: we think 1799,- is an error listed on the ACER website, and expect it to be 799 USD as that is what the monitor can be found for in retail.
