The "make a new cloak" thing was a rumour.
It is highly likely they will be of value in future events. Their use is already known: You enter the Ethereal Void with one on, all those de-gens turn into RE-gens (except karma, it still sucks that off you like a vacuum cleaner).
Though odds are people will complain about this, because they couldn't be bothered doing the work required to obtain them when they were available.
Frankly I hope such complaints are ignored, though it wouldn't surprise me if the result is that the cloaks become available again (hence screwing over everyone who currently has a chest full of the things, a group that doesn't include myself).
