From the photos, it sure looks like the new Warcrafts have skeletonized handles, which I didn't realize. Remember that GSM completely redesigned the Warcraft models after acquiring Cold Steel. So it makes sense that the tang cutout was incorporated during that production transition, not necessarily to save money but rather weight, since the original 3V Warcrafts had tapered tangs and the GSM versions have full-thickness tangs.
The short-lived Italian 3V Medium Warcraft (the only model made in Italy) was introduced prior to the GSM sale and did not have a tapered tang (or at least not a significantly tapered tang).
It was faithful to the original design in all other respects, though, so I doubt its tang is skeletonized.
While I agree that the cutout in the new Warcraft tangs is kind of disappointing, and that GSM shouldn't advertise them as full-tang when they're actually skeletonized, I also agree that the cutout isn't going to make much difference in normal use. If you're considering a GSM Warcraft for combat (or something equally demanding, such as getting Likes on a YouTube video...), then it might make sense to look elsewhere. But for most other uses, I think the hollow tang will be fine.
And if you've got a 3V Medium Warcraft on the way (either Italian or Taiwanese), by all means don't cancel that order! It's a fantastic knife, and they are becoming quite scarce.
