I think with these new giant figures, WotC is trying to get the scaling to be more correct -- or at least more in line with the 5EMM. A 26' storm giant should be 5.2" tall in 1/60 scale and make the party look like yapping terriers in comparison.
Making the "boss" giants larger may be a bit overkill (the morbidly obese Chief Ghu is actually considered Gargantuan instead of Huge), but seems to be intentional to make them even more imposing than the run-of-the-mill giants.
Intermixing previously-released giant figures with these is going to be a GM judgement call, though. I only had a few giants before -- and they look puny compared to this new batch. Maybe as someone suggested earlier, you use the runts kind of like you would goblins: make them sword fodder and pull down their stats a bit.
