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.

Any idea *why* there should be such a 'young' volcanic area there?

The youngest lava flows, maybe 1.5 billion years old, tend to have sources in the broad region around Aristarchus crater in eastern Oceanus Procellarum, with patchy distribution and flowing in various directions out from that general region.  One source in the Euler region (NW of Copernicus in southern Mare Imbrium) produced flows which ran all the way to the Chang'E 3 landing site.  Other young flows are found south of Aristarchus itself, and these at Rumker probably have a source north of the Aristrachus Plateau.  The concentration here MIGHT be caused by the elevated amounts of radioactive materials associated with KREEP, an unusual material sampled by Apollo and found around that region.  KREEP was sampled, but not the young lava flows.

(unofficial news) According to the weibo of ChinaSpaceflight, Chang'e 5 might be delayed to 2019.

Note that this is the only source that gives any info on this till now, based on their own sources. While I think it's certainly a plausible plan on the table, I think it's far too early to declare a 1.5+ years delay, especially since we don't know what failed yet.

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。

The 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.

True, but at least he is a reliable insider in the program management end. What this means is there is at least no immediate decision to delay the CE5 launch. It does not mean they won't delay it later, but at least for now the schedule is end of this year.
