There might be an Elite 7, but it will not be around the Lake. Elite 6 will have the premium location of all the Elite projects.
As for plots around the Lake, some are vacant facing north, north west but these have been held by the master developer I am told.( Look at the photo I posted on the 'Sports City Anyone' section.
If you are looking to buy around the lake I would recommend you look at what is currently available...prices are also rising.
