No this looks very promising!!
...
The only usable fix is using a regular, but even so, the regulator freezes if it gets too cold. So unless they put a sizable regulator in there to let CO2 expand in there, the gun will be cold....
Paintball guns suffer cool-down a lot more because they use a large volume of gas, they are ~15 times more powerful

To expand on that a bit more: the problem is mainly because airsoft guns that use CO2 are flow-regulated rather than pressure-regulated. Flow-regulated means the CO2 just comes straight out the capsule at 800-1000psi but it's a tiny amount. If a pressure-regulator was used instead performance/constancy would be better and cool-down would be reduced.
Fingers crossed for pressure-regulated mags, I'd pay the bit extra for those!
AK mags could take a good 2x 12g capsules too.
