Perhaps I'm misreading the situation, but the fact that SIG and TV are announcing sale of their NGSW guns and ammo on the civilian market before the winner of the NGSW competition is announced, says to me that both SIG and TV expect to lose. 

"Currently being considered for adoption by the US Army" makes a much better sales pitch than "Rejected by the US Army."

They're getting a full 3350 objective in the rifle version while still retaining backwards compatibility with m240.

3350fps with a 135gr? That would be pretty stupendous. 

I think by now all involved know NGSW project is going no where in regards to adoption by the military. But if put on the market and actually getting some traction , the US army might circle back with a new project that recycles bunch of off shelf offerings . That is a trend when it comes to US military development projects.

Hmm.  If NGSW adoption is going nowhere, how do you explain why the Army recently awarded Winchester a $20 million contract regarding NGSW ammo production at Lake City?

Is it?  Can you cite any examples of US Army small arms programs that resulted in no winner, but one or more of the candidate weapons were later adopted as off-the-shelf items?

Maybe the M203 from the SPIW program, and the ACOG from the ACR program?

But I agree that SIG and TV announcement to release both weapons & ammo on the public market is a kind of "world-first".

We had to wait until the release of the ACR report to find that if HK G11 and Steyr ACR were never pushed to any other military market, it was because the root concept for both gun was not sound.

Sure, there have been instances of bits and pieces from cancelled small arms programs being adopted later, but I'd hardly call it a "trend."

And I don't know of any cases where the rifles or machine guns from programs like SPIW, 6mm SAW, or XM8 Carbine were later adopted.

The non-fixed chamber in both guns was also not sound or just the cartridges?

Would G11 have been adopted by Germany if the reunification had not taken place or was it a myth?

Myth or fact, Germans are probably lucky the G11 did not get adopted.  How would soldiers have carried spare magazines -- in a quiver on their back?   

The ACR report had pretty abysmal accuracy for the G11 and Steyr ACR, so I doubt it. The G11 also had other issues, such as the receiver filling with flammable gas as a byproduct of its ceaseless propellant and sealed action.

Yeah those mags are like 15-17”long so would have been a big hassle.
