There is no timeline but I think given an infinite amount of time, no one is going to do it regardless until there's not another option... If you plan on taking it on and giving yourself a deadline I'd happily support a postponement of any decision, but we cannot impose or assign this, no one has stepped up, it is unlikely anyone will step up, and I cannot see even someone who steps up actually delivering a comprehensive report. Alas, these are the shortcuts we must make until we develop a TWC economy...
