.224 Valkyrie? Future competitor to the 6.5 Grendel?

[NOTAR520]

The number they're showing is 2700fps mv, but we don't know the barrel length. Some say 20", some say 24".

From the 6.8 forum

Here it is straight from a Federal employee-
Justin Johnson 90gr at 2700fps from a 24" barrel. We are getting 2630 to 2650 our of 20" gas guns. #federalemployee

I would like a rifle in either 22/6.8 OR 6.5G case
I also would like to see what shakes out with a 6mm variant too!!

6.5G case would offer more powder?
