BENQ have recalled all screens to the factory because there are problems with colors on some batches. That's why it is hard / impossible to find one in stores right now. They told me they are working on a fix for the problem and hope to have the screens back in store soon.
Acer has now also officially announced the Z35 screen based on this 21:9 144 Hz curved AMVA panel from AUOptronics and they claim it can be overclocked to 200 Hz (when using G-sync)
