First of all, this scale lends itself for the manufacturer to add more detail and use different materials compared to the 1/18 scale figures. From what I've seen so far, I like the overall look of Luke and did I see the R2 somewhere online as well?
However, I have no interest in this line at all. Zero. Nada. Zilch. Hasbro stating this line is for the 30-40 years old dads of today, is just rubbish, in my opinion. Being one myself, I grew up with the Kenner figures, and like DarthDaddy, the 3 3/4" figures are all that interest me.
I don't really uderstand Hasbro's move to 6" either. Over time, many lines have transitioned from whatever scale to the immensely succesful 3 3/4" format. That scale is just perfect for combining playability with articuation, sculpt and collectibility. Imagine the space needed to army buid 6" Stormtroopers.... And of course the possibilities for creating additional vehicles, ships, playsets are abundant. Sure, true scale has been and will be an issue, but one has to compromise between playability and correct scale.
With a 6" line, we can only expect to see figures. I don't see an X-Wing coming for that Luke. Maybe a Speeder Bike or something like that, but that would be about it.
From a customizer's point of view I can see some advantages. Apart from the Marvel Legends figures, a lot of the other lines are pretty hard to come by, at least for me. Having a SW 6" line will add more diversity for the 6" scale customizers. That is, if Hasbro manages to actually get their distribution right....
The latest CAFN episode also addressed the lack of articulation and detail in 3 3/4" figures lately. Don't Force choke me on this, but I actually can see where Hasbro is coming from, regarding the downsizing of p.o.a.. Back when I was a kid, I played a lot with my figures. A lot. This often resulted in joints becoming loose eventually. If you play the heck out of your 16 p.o.a. figure, you'll eventually get a lot of loose joints, to a point where playing with it isn't fun anymore.
Then again, these days kids don't care about action figures anymore, which makes Hasbro's reasoning redundant.... As a customizer, I guess I should follow Sithfire's lead and heavily develop my sculpting skills, buy a Sith load of articuated base bodies and go from there.
On that Luke figure again, I find the lack of a holster and a decent '77 Mark Hamill headsculpt most disturbing....
