Sense 5 is confirmation Google Now should be the Android homescreen

Sense 5's "Blink feed" is confirmation that Google should have Google Now as Android's homescreen.

Google Now could be enhanced to show the latest news and social media updates, along with all the amazing things that it does now (love the travel time prompts for upcoming appointments). As a homescreen it would wipe the floor with anything out there - grids of icons won't stand a chance! What do you guys think?
