I think I like the new icons. I hope the continue and complete all the icons.
I don't know if it's just me but metro UI 2.0 seems very reminisce of android ICS.
Although, I'd prefer they go the whole nine yards with the iconography, let's not flatten out old Aero iconography in File Explorer, let's completely revamp them to something ACTUALLY modern looking. That iconography makes me think of Windows Whistler beta or something...
I love the new icons.. it has adds a fresh look to the OS.
