Given that the Revolution Pro Shop at Gillette had extremely low stock of the white secondary jerseys at the end of the season (the home navy tops sold out), I for one would not be shocked if the the Revs debuted both new primary and secondary kits next season, especially with the rebrand effort.
The pro shop was not replenishing their supplies, which is either due to issues with the supply chain (not unheard of) or with the intention of ensuring the current supply is gone before the new stuff comes in.
