Haven't heard anything. You hoping for a 7 based on the 300? Or a shorty based on the 6.5?
My interest is in th 7 based on the 300 prc. Hornady get is right in their cartridge development. Ideally, we pick a bullet that has the characteristics we need and then build a gun around that bullet- choosing the components but also the chamber dimensions to suit the bullet we are building around. Hornady designers have designed bullets with superior flight characteristics, then designed a SAMMI cartridge around that bullet. The end product is the Creedmoor family and the PRCs.
When the 7 PRC is released it will put out-perform the Nosler with less powder and pressure in a SAMMI cartridge that was designed around the 190 A-tip.
I am interested in seeing the BC of the 190 though!
