NO THEY DON'T FIT THE NEW 2011s.
I just emailed customer service @ WeatherTech the other day. And they said that NO prior year will not fit the new 2011. If you don't believe me you can email them yourself, they responded to my question that same day and were very clear.
The new 2011 floor liners are in production, I was told that they will be ready in 3-4 weeks. You can sign up for a reminder, and when they are ready for purchase they will email you. This is the link to sign up for "product request" they will email when the new 2011 mats are ready.
