For Android L devices, it has been reported that the device might
power up its screen fully (note I didn't say 'wake up') automatically
when it detects that you are picking it up, or when you double-tap the
screen. It also reportedly has a low power black and white "ambient
display" (ala the Android Wear devics) which allows you to see
notifications without waking up the phone all the way[1]. (All of
this assuming appropriate hardware support, of course.)

Which goes back to the concept of having a "suspend" mode is legacy
thinking. Modern devices will soon have not just a "awake" and a
"asleep" modes; there will be (well, is now) a much wider spectrum of
modes, with the goal of using the minimum amount of power while still
providing use functionality to the user.
