"the book you're reading, the game you're playing, or the movie you're watching"

I'm confused, PDFs, games and movies already are full screen on previous android versions.

On my N7, reading replaces the action bar with faded out dots. I'm assuming that in 4.4 the action bar disappears now too. I've read that you swipe from an edge to make it reappear. I'm interested to see how edge swipe heavy apps (Kindle) will handle it.
