The last time we saw Ghost of Tsushima was in E3 2018, and the very short teaser above unfortunately doesn't tell us much about the game's progress.
The good news is that in 3 days, it should appear at the Game Awards according to Geoff Keighley, the master of ceremonie.
As a reminder, Ghost of Tsushima has no release date yest, and it's only scheduled for PS4 at the moment.
Sony have shown a final State of Play for 2019, on december 10th. We've got 20+ minutes of PlayStation news, game reveals, and updates, so here are all the announcements made.
