I think that the only really decissive factor is cartridge technology and form factor.

I mean that's clearly not true. They can get everything else right, and the program will still be a failure if they've made significant enough errors in the fundamental parameters.

FInally is the weight saving

Which is a lie.

Beretta / GD vocalism on bullpup as a solution for achieving muzzle energy without needing a meaningful pressure leap makes me assume that true velocity solution is not optimal for pressure increasing.

It's not, but CT isn't optimal in other ways. For example, cartridge mass.

Textron is an all-in solution, the less compromised one. If the main problems are solved for assault rifle, I would assume than the less compromised is a solution, the bigger growth margin it has.

If the main problems are solved.

1. How can we know the mass of CT or TV cartridges? Or weight savings?

2. Can TV cartridges admit as much pressure as CT? For instance, moving into magnum territory, can extraction groove resist when it is inserted into plastic walls?

1. By modeling them.

2. Probably not, but I'm testing that with FEA right now.

I think I saw the SIG AR in there too.

*edit* No, it was the Textron.

Interesting that both the Textron and GDLS AR and carbine were shown being tested, but not the SIG. It could be coincidence, I guess.
