Well, as it turns out, the bottle is not only real but we managed to snag some early.

The bottles are a new Mixed Berry flavour, although the bottleneck calls them "Goalberry". There's also some new text on the side that reads:
"PRIME WAS CREATED FOR THOSE THAT STRIVE FOR ICONIC. TO FILL THE VOID WHERE BOLD, IN-YOUR-FACE FLAVOUR MEETS LEGENDARY EXPERIENCES. INTENSE AND REFRESHING, PRIME IS AN ULTIMATE QUENCHER TO CONQUER YOUR DAY. WE'RE CONFIDENT YOU'LL LOVE IT AS MUCH AS WE DO. HUMBLY, THE PRIME TEAM".
Those wishing to get their hands on one soon shouldn't have to wait too long as the bottles barcode has been spotted on numerous retailers stock systems - chiefly ASDA and Sports Direct in the UK.
We don't know the exact date of when it will arrive, but as soon as we know, we will post here and on our socials - so keep your 👁️'s peeled!
We made a TikTok about the bottle showing it off in more detail - here it is if you're interested:
