3Dementia makes a good point about a hotel component. The current rendering isn't spectacular, but makes good economic sense, since (correct me if I'm wrong) this design is not for a corporate headquarter, and therefore there is no requirement in the design for corporate recognition. I assume the only requirement is to create a building that is cheap to build, and provides the most floor space, and the best way to fulfill that requirement is to build a box.
A hotel/residential component would allow a much more creative floorplan, and also a more creative building shape to attract buyers or residents. If a hotel component can be added to the office building, the whole thing might end up like 1 King West, with two distinct building components.
I have no clue what 3Dementia's photo is showing... a bunch of Arab sheiks looking at a site model with the Oriental Pearl TV Tower, the Bank of China and the Petronas Tower? Are they trying to build all of them at once or something?
