'Robocop' delayed?

According to RiskyBizBlog Darren Aronofsky could shoot supernatural horror 'Black Swan' later this year (Natalie Portman is already cast in the lead), which would push production on Robocop back to mid-2010. The delay could still conceivably see the film hit screens in 2011 ,as previously planned.
However, it's also making MGM nervous, with the studio apparently "quietly putting out feelers for other directors who could come on to Robocop in case the timing doesn't work out."
