Well I've reviewed the presentation by Ouyang Ziyuan at the China Academy of Science in June, and it has a list of instruments to be carried on board the lander and the rover. Three of the instruments are definitely worth mentioning:
1. The lander will carry an optical telescope (probably not that big, around a dozen cm in diameter) that would conduct the first ever astronomical observation from the lunar surface (well, the later Apollo J-class CSM came rather close....). This telescope will operate in the near UV region, and will target close binary stars, active galactic nuclei, short-period variable stars etc.
2. Also on the lander is a far UV region camera that will observe the 30.4 nanometer band radiation from the Earth's ionosphere, another first in lunar exploration. This will monitor the effect of space weather, solar activity, Earth's geomagnetic field and particle streams on the Earth's ionosphere.
3. The rover will carry a radar on it's bottom side, allowing for the first direct observation of the structure and depth of lunar soil down to 30 meters deep and the lunar crust structure down to a depth several hundred meters.
Other instruments include:
Lander: 3 x panoramic cameras, 1 x descent camera, 1 x extensible lunar soil probe, 1 x lander engineering package, 1 x lander data controller
Rover: 2 x panoramic cameras, 2 x navigation and engineering camera sets, 1 x alpha particle X-ray spectrometer, 1 x infrared spectrometer, 1 x lander engineering package, 1 x lander data controller.
The lander phase is rather conventional, but it includes a 100 second hovering phase for the lander to take photos of the landing area and find a flat spot for landing.

(CE-3 part starts at 208 minutes)http://www.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=451&pid=166465
Meanwhile, the engineering model of CE-3 was transported to XSLC in June for practices of the launch campaign, still on target for launch next year. This is one of the reasons why no launches were scheduled from Xichang last month.
