I don't think anything substantial will get built there soon though since only stuff still under construction will get built. Nobody is launching new projects (well, very few anyway).
The whole of Dubai Marina is like a suburban neighbourhood (a very large one). The reason is that very little of this crazy development over the past few years has been infill. Instead there were lots of master-developments such as the burj dubai district, dubai marina, etc where smaller developers bought plots to build towers, or midrises. There are midrises in the marina by the way. The reason why all the biggest towers are clustered together is Emaar (the master developer of the marina) noticed all the towers were being built up to the maximum height allowed by their plots so they decided "hey, if we make these plots unlimited height then we can sell the land for more" so they did, and now we have 300, 400 and 500m towers all clustered together. Why they didn't spread these unlimited height plots around the marina is beyond me.
At least with the metro, people can cross from the marina to jumeirah lake towers by foot using the foot bridges.
Princess Tower, The Torch, Elite Residence and Marina 101 are definitely cookie cutter. Infinity Tower, Pentominium and Ocean Heights are great though.
