I hope so, if I remember correctly, we did not see any XB1 Horizons gameplay until the evening before release.
I don't own a PS4 but I will be extremely interested to see it running on the platform.

On the first day of PAX (Friday March 10), Ed will be joined by Lead Designer Sandro Sammarco for two 1,5 hour-long streams live from Boston; we will be talking about some of the newly released content from the Elite Dangerous; The Commanders (2.3) beta and taking a closer look at the PlayStation 4 update coming this year.
