PC Gamer reported on October 28 that Parsons is currently busy with three projects he describes as dream projects.

The hoodie is what drew the attention. PC Gamer's headline flags the Valve apparel as suspicious, and its writer jokes that Half-Life 3 would end up a patchwork of YouTube shorts.

That is where the evidence stops. The source names no Valve project, no collaborator and no studio. What the three projects are, which formats they take and when they might surface has not been stated. A piece of clothing is the only link to Valve.
