New 3-Series

I have a '91 E46 M3 with 130,000 miles on it. Time for a new car. I would like to buy a new 3 Series, but it may make sense to wait for the new model (post E90/1/2). When is the new model due to be released?

Best guesses run to autumn 2011 for the sedan, a year or so later for the coupe.

I think SOP for the US F30 is going to be March 2012, and it will be a 2013 model. They should be available then sometime in April 2012 here in the States.
