Honestly, without some finished products and being able to see what the actual case will look like, I would say this survey isn't going to add much, as not much has changed probably since the first color poll. I understand why black is always on top, as it's the most neutral color I suppose, as that is why it is probably the most used across gaming. I personally can't stand it, as it's just so plain, but that's my own personal issue.
The only other logical color at this point would be the dark red that is shown for the Pyra on ED's site. It's been the only real color used on a regular basis, and most who have pre-ordered probably see it as an option(since it's in the promo pics). That color as it's shown is great, and that will be my option if offered. The yellow mock up was my favorite, but that is very niche and won't happen unless the Pyra gets to a point where custom colors can be offered on demand, but I don't see that happening anytime soon, if at all.
I'm also very fine with clear, and plan to order a case when offered. I've actually done many clear case mods over the years, and I love the concept. My only issues with clear is light bleeding through where it shouldn't be(mostly around the screen), as it can be distracting at times. With the Pyra having so many light sources within the unit, I'm worried how this may play out in the end, but for now I'm hoping it will be OK.
So I guess this all depends on how many options ED can offer at launch. If we can get 5, that would be great and then a survey is needed, but only once we can see what the final products will actually look like. As without that, it's pretty much a wish list with not much basis in fact at the moment.
