I got to say, pretty awesome that GT will be getting its own State of Play. We are very lucky to be getting such a large preview, before release.
As far as I've seen, only a handful of games of even got one all to itself. Demons Souls had its own less than a week before the PS5 release, then Horizon Forbidden West had one last May, and now GT is about to have one a month before its release.
The most shocking part, is that the presentation is advertised as being over 30 MINUTES long. That's crazy, longer than most normal 'State of Play' event dedicated to just small trailers. The longest so far prior to this dedicated to a single game, was Demon's Souls at 12 minutes... but that was edited a decent bit. I'm gonna predict this will be a prerecorded, mostly unedited 'walkthrough' with Kazunori himself and subtitles.
