We've known that this was likely to be a flavour for a little while now and aside a few obscure references and website listings - we didn't know if it was 100% real - but not only is it real, but it will be coming in two forms - Hydration and Hydration+ Sticks. See images below:


We also have a release date of the 29th February!
Limited Edition Bottle
But wait... there's more. What would a new PRIME flavour be without a special limited edition bottle?
Accompanying the two new products will also be a limited edition "Scratch & Sniff" bottle. A preview of which can be found below:

The gimmick with these bottles being that you'll be able to scratch the bottle and it will make a strawberry-banana-ey smell I guess? Still cool though and always good to see innnovation in products rather than just a drink.
When these will be released is unknown yet (given that we still don't have the limited edition of Cherry Freeze yet fully) - in the meantime though here's a trailer for the new flavour and new limited edition bottle:
