Is NX1060P070_011 a product?

I see that the Nextion editor supports a 7" 1024x600 intelligent display, NX1060P070_011. This would be very handy for one of my projects, where the 800x480 models would be a bit lacking in resolution.

I can find no other reference to the NX1060P070_011 anywhere, including on the official Nextion web site. Does anyone know if the NX1060P070_011 just vapourware that never made it into production or if it is likely to become a reality at some point?
