I don't think this is likely. The young basalts near Mons Rumker are a very important goal for CE5. The second sample return mission, CE6, is much more likely, in my opinion, to go to a farside site using the CE4 infrastructure. There is now talk of two polar landings after CE6, in addition.
(unofficial news) According to the weibo of ChinaSpaceflight, Chang'e 5 might be delayed to 2019.
Ouyang Ziyuan said in his most recent interview where he supposedly said "to the best of my knowledge, there has being no change to CE-5 launch plan (due to the recent CZ-5 failure)." He further said, any test flight will have problems, and our engineers are capable to find and solve these problems.几天前,长征5号火箭发射失利引发国内外媒体高度关注,因为长征5号年底即将搭载嫦娥5号进行中国无人探月工程的最后一步,一些媒体猜测嫦娥5号发射进程或将受到影响。欧阳自远对此也非常关注,但他说,从他了解的情况看,嫦娥5号发射计划目前没有改变。“刚刚实验的是长征5号第二次试飞,第二次试飞很遗憾没有进入到预定轨道,我们的工作是难免有这样那样的缺陷,我们一定会从失败当中吸取教训,改进工作,提高质量。”欧阳自远说,任何试飞都会出现一些小问题,但中国航天部门广大的科技人员有实力解决这些问题。https://kknews.cc/news/pxq439p.htmlhttps://weibo.com/6243310541/Fc4abdBhX?type=commentThe interview is part of a forum-lecture, so hopefully we should see the actual video of exactly what he said once it is scheduled to air.I wonder if this mean they have root cause the problem and it is not related (or used) in the CE-5 launch.

Jeff Foust @jeff_foustXiao: no official launch date for Chang’e-5 (delayed by Long March 5 failure); guess need 1-2 successful launches before it. #leag2017
Jeff Foust @jeff_foustXiao: next phase of lunar exploration program will be series of polar missions, including sample return, in early 2020s. #leag2017
delay to 2019

According to the emerging schedule, a successful launch of the third Long March 5 will see the fourth rocket launch Chang’e-5 to the moon in 2019. The complex mission aims to land in Oceanus Procellarum and collect 2 kilograms of regolith. An ascent vehicle will then perform a robotic lunar orbit rendezvous and docking with the service module and head for earth, with a skip or boost-glide reentry seeing the return capsule set down in Inner Mongolia.

Space manipulator has been playing an increasingly important role in space exploration due to its flexibility and versatility. This paper is to design a vision-based pose measurement system for a four-degree-of-freedom (4-DOF) lunar surface sampling manipulator relying on a monitoring camera and several fiducial markers. The system first employs double plateaus histogram equalization for the markers to improve the robustness to varying noise and illumination. The markers are then accurately extracted in sub-pixel based on template matching and curved surface fitting. Finally, given the camera parameters and 3D reference points, the pose of the manipulator end-effector is solved from the 3D-to-2D point correspondences by combining a plane-based pose estimation method with rigid-body transformation. Experiment results show that the system achieves high-precision positioning and orientation performance. The measurement error is within 3mm in position, and 0.2 deg in orientation, meeting the requirements for space manipulator operations.
A sampler carried on the end of the manipulator was designed in view of the sampling task of the lunar surface regolith. Based on the discrete element method, the parameters matching of the simulation particle characteristics was completed by using the data of the miniature three axis compression test data of Scott real lunar regolith. The simulation analysis of the sampling process of the sampler was carried out and the dynamic characteristics of sampler during the working process were obtained. In addition, the performance test system of sampler was set up. The sampling test was carried out for different simulated lunar soil. The test acquired the sampling capacity of the sampler changing with the depth and the lunar soil hardness. And the feasible region of the sampling device's operating parameters was obtained by testing. The sampler can achieve the multiple tasks of transferring encapsulated containers, shoving and excavating. The research work will provide reference and technical support for future lunar sampling missions in China.
Here is a PR piece about the Chinese space program that just came out today: news.sina.com.cn/c/2019-07-09/d… (in Chinese). Typical stuff, until the end where it mentions the launch date of the #ChangE5 mission will be "circa 2020".
