The main question from fans as of late - when will PES 2017 demo land? - has finally been answered: Konami has just dated the demo version of Pro Evolution Soccer 2017, which will be available to download starting August 23/24. The announcement comes at the end of this new PES 2017 Gamescom trailer:
As you can tell by the attached screen, the demo will be available to download next week (Tuesday in America, Wednesday in Europe) on PS4, PS3 and Xbox One, while PC and Xbox 360 are left out this time around.
The announcement also confirms the nine licensed teams available in the demo, in order of appearance: SC Corinthians Paulista, CR Flamengo, CA Boca Juniors, CA River Plate, FC Barcelona, Club Atlético de Madrid, Arsenal FC and the national teams for Germany and France.
Thus Gamescom-announced new "PES family" partner teams, such as Liverpool and Borussia Dortmund, content for which will be added post-launch via a free update, won't be part of the demo.
