On June 10, 2016, Sony confirmed that a hardware revision of the PlayStation 4, rumored to be codenamed "Neo", was under development. The new revision was revealed to be a higher-end model meant to support gameplay in 4K. This new model was sold alongside the existing model, and all existing software was compatible between the two models. [38] Layden stated that Sony has no plans to "bifurcate the market", only that gamers playing on the Neo will "have the same experience, but one will be delivered at a higher resolution, with an enhanced graphical experience, but everything else is going to be exactly as you'd expect". [39] The high-end console was publicly revealed on September 7, 2016, as PlayStation 4 Pro. [40] At the same time, Sony unveiled an updated version of the original PS4 model with a smaller form factor. [41] Byford, Sam (November 25, 2015). "PlayStation 4 sales hit 30 million worldwide".
