Their concern is not completely unwarranted. A lot of us has lived through re-boots and remakes that either made the game worse or just lead straight to abandonments.
I do not follow this thread closely, and did not know about the announcement, but even if I knew, I would not be unconcerned about the remake.
We have seen this story before, and even though it is probably not going to happen here, I would personally sigh a breath of relief once the main story resumes.
A reboot/remake, even though the intention is good, is something that makes people jittery and impatient and the surrounding negativity could demotivate the developer and often leads to the game being abandoned.
Instances where I felt more at ease, were where completely new content gets rolled out, together with reworked earlier chapters.
TLDR Even though this is planned, it's still making me nervous.
