Sony revealed their plans to abandon having a press conference at Gamescom this year. Before you go into full on panic mode, they do have a good reason for it and they also reveal that they will instead hold a conference at Paris Games Week.
We’re delighted to announce that we will be hosting an international media briefing at Paris Games Week on 27th October. With the changes this year of E3 taking place a week later and Gamescom taking place earlier, we feel that both PlayStation and the wider industry would benefit from a major news milestone later in the year, during the most important period for gaming. We are excited about our plans and look forward to sharing some exciting announcements. We will share more information closer to the time.

See? It's a perfectly valid reason.
