There sure are. The old United Founders Tower (the cool circular black and white building) is being converted to 68 units, and they are replacing the black colored windows with light bluegreen ones. Each unit will have THREE balconies and they're offering incredible concierge services from what I gather. The revolving restaurant Nikz at the Top is staying.
This pictures shows that they've started replacing the windows. The building will look like brand new when they finish:
The land around the 360 will feature a new office building and they're talking with a few hotel chains to put a hotel on the location.
W, Hyatt, and Hotel Indigo have expressed interest.
There is also a proposed 11 story condo tower called the Lighthouse near the Expressway overlooking Lake Hefner.
