They already have come along PRC's but who cares ?. Just like 7 Rem Mag in 1964 when I bought mine ,oh that's just a fad it will go away . I still own MY original 3000L Mauser and it looks nearly as good today as it did then
Only NOW it's worth far far and away more $$$$'s than it did then .
I personally like guns which shoot small groups ,don't care if it's 25 yd. or 1500 yd. , some cartridges do it better and more efficient than others .
The 6.5 Creedmoor is just one of those cartridges ,not unlike the 6.5 Swede they just fill a necessary void very effectively .
Do You realize the most versatile cartridge to ever hunt African game is still the 7mm Mauser aka 7x57mm . I wonder how many hunters said oh the larger 500 Jeffery or 505 Gibbs will eclipse it . Not even the 8x57mm aka 8mm Mauser did ,nor the 577 or 700 Nitro express's did .
