If the screen is OLED (due to the new animated wallpapers that Jony Ive only likes with OLED screens), then I can see them making it 1080p now rather than waiting until next year. They changed the screen last year, then they would change it again this year (if OLED), then again next year for 1080p? That's too much if you ask me, that's why I think it's certainly possible, but only if the screen is OLED.
