I only collect 3.75" Star Wars figures.
Sure I collect a bunch of NECA/McFarlane/DC stuff, but that's around 7", and doesn't mesh in any sense of the word with the 6" Star Wars stuff. So I haven't bought a single 6" SW figure. I'll admit they look cool, but I'm just not interested in starting over my many-thousand figure 3.75" collection at 1:12 scale. For me Star Wars is just as much about the vehicles and creatures as it is about the people, and the 6" line isn't going to have that in the same way.
