I can't track down the reddit posts atm, but it never went out of stock on Newegg. It's just the SKU that was originally released, when the "gaming" version was released a few days ago Newegg just added a "there is a newer version of this product" but still sold the original SKU.
The wording of their post does corroborate it as well though.
"The ship + sails are here to stay and will continue to be used on all Corsair PC component products. " - We all knew this already, it's only "gaming" peripherals that fall under the new Corsair Gaming division.
"For those of you looking for the new K70 RGB with the original sails logo, it’s currently available in North America from Newegg – just look for the SKU CH-9000063-NA." - It's currently available, but has also been available since K70 RBG release.
"What’s more, as a direct result of your feedback, we will continue to sell and manufacture the Vengeance K70 and Vengeance K70 RGB with Cherry MX Red switches, with the sails logo, via select retailers and Corsair.com." - This is the only "direct result of your feedback"
Also don't forget about this forum post:

"Here's what it boils down to. The logo is NOT going away. We have a plan and we're executing it. Period. "
