Not 100% yet, but if I were to give an exact date off of what would make sense and what I was told, Iโd say announcement Tuesday, June 23 at 10AM PT, and reservations Tuesday, June 30 at 10AM PT
To quote exactly what my source said; โTheyโre allowed to post videos after June 23โ. Going off of Steam Controllerโs announcement, the review videos were put out the same day as the announcement.
Might be worth it to check here June 22-23, if not then another day between June 22 and July 1, but this is what would make the most sense considering the embargo.
1. Announcement for Hardware reservations and prices expected between Jun 22 - Jun 30
2. Reviewers are actively receiving Steam Machine and Steam Frame units (see enclosed photos)
3. Steam Machine comes with a Steam Controller, 2 mounting brackets and a Steam Machine in a box.
4. There are separate boxes for faceplates (unsure if shipping by default)
5. Creators embargo seems to be due to lift on Hardware reviews after Jun 23
6. Unclear whether Steam Machine and Frame are launching simultaneously, likely
