I've got a Metallic Grey PS3 controller that I absolutely love the hell out of, if that Steel Black is the same finish that thing is gonna be hot fiya. The Gold looks really damn nice too with the black complementing it.
Missed opportunity on the Silver, it would look a lot better against a black backing.
Crystal's... naw son. I'm rather biased against transparent electronics, though I actually think a DS4 could be kind of cool if it went either entirely transparent or had a transparent back panel. The sensor light would probably make the whole outer rim have a glow to it, which could be a pretty cool effect, especially with some games' dynamic sensor light changing.
seriously
I wonder how many of the OMG TRANSPARENT GIMME posts are people who really want to turn the LED off. this clear shell will only amplify the effect.
No it won't. The light doesn't touch the front panel and it doesn't shine backwards into the innards of the controller. Too bad, as a bit of glow showing would go far to redeem the transparency. There's lots of games that use the sensor light to indicate health or various things (reflecting your team color in Rocket League is a cool one), but you never even see the dang thing unless you play where it's reflected in your TV, and that certainly isn't ideal.
