Budding Horizon collector here - found this post while looking for an HFW press kit (which as you say sadly doesn't seem to exist).

Here are a couple more HFW merch posts I was able to find on social media.

Huge merch assortment:




And a closer look at the backpack:

Three of the four T-Shirts and the water bottle seem to be retail merch from the Sony Gear Store. But the hoodie and rain jacket should be exclusive influencer/press gifts.


Another influencer haul from here:




No new items, but it's interesting how the types and numbers of goodies vary between influencers.


And this one might be the most complete haul, yet:




Looks like it came in a neat box.

Also managed to find a few videos:

• Unboxing of the big merch box. Looks like they come with a thank you card addressed to the influencer. No indication as to whether it's named or numbered, though.
• Another big box
• another one
• another one
• Unboxing of a smaller tote bag type influencer kit

Some backpacks and other items also have found their way onto eBay and are fetching pretty crazy prices:

This description says that they were given out to Sony associates to commemorate HFW's release.

And finally, I managed to find this overview on the manufacturer's site, showcasing most of the merch, with the exception of some preorder bonuses:




Happy hunting!
