The great info is that both games on Xbox One will be in 1080p/60fps. We heard that by Julien Merceron, involved in the development of Konami's Fox Engine. Thanks to the new SDK, developers were able to upgrade low resolution textures to high definition ones. Ground Zeroes and Pes 2015 were both 720p resolution on Xbox One.
