Leaked product images published by Footy Headlines on August 28, with a September 2026 window and no street date; the Adidas and Croatia kit deal was announced August 1 and is independently confirmed.
Footy Headlines leaks Croatia's first Adidas kits, launching in September after 26 years with Nike
The home shirt keeps the red-and-white checkerboard with subtle Glagolitic-script detailing, and the away is EQT Blue with red applications and a white Trefoil. Footy Headlines puts the launch in September 2026, timed to Croatia's September 24 national team camp. Treat this as a credible leak rather than a listing: the images are Footy Headlines' own, no exact street date or price is stated, and neither Adidas nor the Croatian federation has announced the product. The supplier switch itself is separate and confirmed, announced on August 1.

Listed as Coming Soon on Panini America's first-party catalog with a live countdown reading 19 hours at the August 31 check, and no date stated on the page. Confirms the product, not the timing.
Panini's Coming Soon page shows a 19-hour countdown on the 2026 Prizm FIFA World Cup Hobby Preferred box
Panini America's own upcoming-products catalog carries the 2026 Panini Prizm FIFA World Cup 2026 Trading Card Box (Hobby Preferred), and the timer on it read 00 days, 19 hours, 00 mins, 12 secs when we checked on August 31. The page gives no calendar release date and no price, and there is nothing to preorder yet: the alert signup is the only action available. Panini's World Cup card programs run past the tournament itself, with the higher-end configurations arriving after the final, so a listing appearing now is current rather than stale. A separate Prizm World Cup box page exists on the same site, but we could not confirm it as this Hobby Preferred configuration, so it is not linked here.

September 2 hobby and September 9 blaster dates listed as estimates, with full box configurations, on Checklist Insider's product page.
Checklist Insider estimates September 2 for 2026 Upper Deck Team Canada Juniors hobby boxes, blasters September 9
Hobby boxes are listed at 15 packs of 6 cards with 12 boxes to a case; blasters run 6 packs of 5 cards with 20 boxes to a case. Checklist Insider marks both dates as estimated rather than brand-confirmed, so treat them as movable until Upper Deck posts its own. No manufacturer price appears on the page either; the only figures shown are secondary-market eBay listings.

September 10, 2026 stated as an estimated and explicitly unconfirmed release date, with six box formats listed, on Checklist Insider's product page.
Checklist Insider estimates September 10 for 2026-27 Topps Match Attax UEFA Club Competitions, the line's 20th year
The new UEFA Club Competitions cycle marks 20 years of Match Attax, and Checklist Insider lists it in Display Boxes, Mega Tin Boxes, Booster Tin Boxes, Multi-Pack Boxes, Starter Packs, and Countdown Calendar Boxes. The September 10 date is explicitly an estimate, not confirmed by Topps. No manufacturer price is stated; the page shows secondary UK eBay listings only. Match Attax is the cheap entry point that pulls in casual soccer fans rather than card collectors, so the Starter Packs and Countdown Calendar are the formats worth watching if you are buying for someone else.
