What you suppose will be awesome features/specs on HTC One(M7)?

Okay so now that only 1 day(approx) is remaining for the possible unveil of HTC One(M7), what do you suppose will be cool features/specs of this beast?(If it really exists)
Let me start,
I think that bigger grills above and below screen may indicate that HTC One may have the option to hear/speak form any one depending how you are holding the phone. It may not be much be much of a feature but seeing that HTC DNA had the notification light on the back too, we can safely assume that HTC isnt afraid to do few unusual things so this might be a possible explanation to those big grills. Also we have people who have specific ways to keep their cell phones in pockets so this may help them most.
What do you think? Is that possible?

What other things HTC might have added to set itself apart you think?

Well now we know lol :)
