Looking at the THS timeline for two reasons.

Pod guns came to Transhuman Space after they showed up in concept pictures for the US Army's "Future Warrior" initiative with a guy in a wetsuit and streamlined motorcycle helmet having a gun and mini-missile launcher mounted on his arm as if he were a BattleMech. The year after that the "pod" had sprouted a pistol grip and pod guns haven't been seen since.

We might already have changed standard ammo calibers with the new 6.8mm SAW if that works out. Migration to smaller calibers for rifle and machine gun ammo seems unlikely now though there are some interesting new pistol calibers under 9mm.
