No. A good idea, but like many 'good idea' cartridges, there are other variables that influence a cartridge's long-term success besides being a good idea and having good ballistics.
Some factors that will slow adoption:
* .Mil chose another cartridge for new "overmatch" rifles. So there's no built-in big gov contract option to drive manufacturing capacity and mass production of ammo.
* 6.5 Grendel, .300 Blk, and similar options that complement plain old 5.56 for different uses (short barrel suppressed, hunting, extended range shooting, etc), already exist. These work well, 6.5G already has very similar ballistics, and both calibers have wider adoption. There are more rifles/uppers/barrels/parts/factory loads to choose from.
I'm interested in 6mm ARC and think it was a good idea. If it starts to get wider adoption and surpasses say, 6.5G, I'll check it out. But due to the above, doubt it'll ever get much traction in the market.
