One tour company in Shanghai has added the fallen building to their site list, a well-timed move that garnered 100 reservations on the first day the new tour was advertised. As you can see in this Fuji TV news report (fast forward to around 1:30), the tour is not so cheap at $220 a head. And not every local is thrilled to see their city represented in failed building projects.
Also, as Japan Probe points out, Fuji TV's graphical representation of the apartment falling is fairly wonderful. Keep your eyes on the upper right corner of the screen for that great moment in animation. [Japan Probe]
