Europe will see the next gen Aveo arrive in showrooms about half way through this year (2011).
Here's one on the road in Germany (EU plates with "D"). Lightly camoflaged - duct tape over the badges!

One thing of note: we've now seen "production" versions of the Aveo / Sonic with both four- and five-lug wheels.
