There are like you say Ali786 a mass of developments being proposed and approved at the moment in the Emirate of Ajman. There is a relatively new project that has not been mentioned in this thread yet called Al Zohrah, it is not so much of an individual project but a new city that will be created by jointly by the government and a private developer. It is going to require investment of approximately $60 billion.
I have created a website with some incorporated promotional video's I ripped from Youtube so if you want to find out more about the area take a peek
