In the last twenty years, the 7mm08 is probably one of the top ten calibers sold in deer hunting rifles. Most that bought them are very happy and will continue to use them. Only shooters that got to have the latest greatest will replace them with a Creedmoor. I have been hearing the same thing said about the 30 30 for 50 years and each deer season you see 30 30 ammo on sale everywhere.
What do you wanna bet that a smart marketing firm could rebrand the 30-30 as the "30 WCF Tactical Lever Magnum" and spike sales? A few videos about the armor plating deer and elk are growing and you'd be in the money...
