It's an official announcement, so I would expect it to happen as planned:

The robot experiment inside Cheops Pyramid in Giza will be repeated next year but this time by a different institution, said Chairman of the Supreme Council of Antiquities, Zahi Hawas. The University of Singapore is currently designing a robot to reach beyond the door which blocked the route of the robot used by the US National Geographic in September 2003, said Hawas in statements on Saturday. The new experiment will be conducted in October 2005, added the SCA head.

I can't see how they will get past the second door without breaking something. If they do start to break things, that's great news, for it will speed up discovery!
