On 22 May, 2012, the ownership of the Golden State Warriors announced a proposal to move the NBA team to a waterfront site on San Francisco's Piers 30 and 32, at the foot of the Oakland-Bay Bridge. They plan to model the financing of the project on the San Francisco Giants' AT&T Park, where no municipal funding will be requested for actual construction and pier improvements, in exchange for a very favorable long-term lease on public lands, and all revenues from retail and parking concessions.
Construction of the 17,000-19,000 capacity arena is projected to cost $500,000,000 and it is hoped to be completed in time for the 2017 season.
EDIT: It's a done deal with City Hall and the City Supervisors. Now it's all about getting approval from all the strange state commissions.
No designs have been published yet, but here are a few renderings of the site (from the San Francisco Chronicle, and Future Cities-- click the link, more detail there):
