Just to add a few more...

The complete Sandridge Commons plan. The Sandridge Amenities Building on the left is under construction now and a completed Braniff Building is seen depicted in the middle of the render, behind the main skyscraper. The new 14 story tower is unannounced but has been rendered in plans for some time now. OKCtalk
New Main Street parking garage announced with retail on both sides on the ground floor. Possibility for added housing on top, but has perhaps been eliminated at this point. OKCtalk
The new Chesapeake Energy Arena grand entrance. It faces the previously elevated I-40 highway that was torn down and relocated several blocks south. This new entrance will now face Oklahoma City's new grand boulevard. OKCtalk
Lots and lots more going on in the central city and Downtown area.
