The finalists are:
-Moshe Safdie and Associates Inc. in association with Sultan Campbell Britt & Associates
Each team received a $50,000 stipend for their competition design. The winner will be announced in mid-April, and they have 3 years to complete the design, as construction starts in 2012 and the museum will open in 2015.
No renderings or images were released with the announcement, so it appears the designs will be under wrap until the winner is announced.
