Well, here's whats happening: (what I've read online)
Emaar hasn't left yet. In light of continuous delays by Emaar (several years) on completing the mega project DHA stepped in took over Crescent Bay. Entire property. DHA plus customers filed law suit and a case against Emaar and they counter sued. DHA wanted to complete it on their own and deliver on time. However, the court gave a verdict in favor of Emaar Pakistan and told DHA to vacate the property plus stop any construction until a clear verdict was given in the legal case.
Now we move to Creek Marina here the story was a bit different. The dispute was between a contractor and management. The management made huge payment to contractor to deliver in time. However, contractor delayed it beyond reason. They filed a law suit against them. Ended on a positive note, management won the case and were reimbursed entire amount plus penalties. The project relaunched just a month ago been and now construction has started again.
In short, litigation = years of drama.
