iPhone 6 Latest: Is This A Glimpse At Apple's Future?

In the absence of any real iPhone 6 leaks or specs, attention has turned back to concepts for the next Apple smartphone. And one has caught our eye that's just a little bit special.

This clip by designer Sahanan Yogarasa imagines an iPhone 6 'Pro' which is not just ridiculously thin, but also has a notification light around the home button, a heart-rate sensor and a… stylus.

Yes, that last one might be a bit of a stretch -- we just can't see Apple releasing a smartphone with a slide-out pen. But it's an interesting idea, and would certainly be a curiosity (if not an outright rip-off of the Note 3).

Take a look at the video above, and some of our other favourite concept images of the next iPhone below.
