From the Pew Brothers:
.380 HST 99 gr at 1030 FPS= 223 ft lbs
.30 Super HST 100 gr at 1250 FPS= 347 ft lbs
9x19 HST 124 gr at 1150 FPS= 364 ft lbs
To me the new round with its length will have to have a larger weapon than the .380. The 9x19 has a wider range of applications(bullet weight). So to me the .30 will be relegated to a niche market.
