Check out this crazy dual-screen iPhone 6 concept

The latest concept features a superthin new iPhone with a second slide-out screen. Is it fantasy or prophecy?

The lead-up to the release of each new highly anticipated smartphone like the iPhone 6 is always marked by a handful of interesting concept videos with some innovations that might not be practical or cost-effective for the mass market, but are nonetheless awesome to consider.

Case in point, the last concept I featured here, which touted an iPhone 6 with a holographic screen.

Hovering a little closer to reality, but still dodging other slices of pie in the sky, is this interesting concept from Sahanan Yogarasa that imagines a superthin iPhone 6 with a slide-out second screen that's optimal for gaming.

This idea gets simultaneously filed under both "awesome" and "too good to be true anytime soon."

The opportunity to double screen space without increasing how much room the phone takes up in my pocket? Yes, please. The notion that this can be done while also making the next iPhone slimmer than ever before (and with both 4K display and video capture, to boot)? Not this year.

Still, I love any fanboy willing to put this much effort into something that should become possible sooner than later. And maybe it's not too much to ask for one of the most valuable companies in the world with billions of dollars just lying around to find a way to make it happen.

Check out the video below and let me know in the comments if you think we'll ever see this in the wild.
