gnr announced it in february last year. ac/dc were supposed to announce it by november 23 already but it got postponed for some reason. apparently to make more room for days off between shows
its' not GNR's fault Creative Works chose to issue that statement. it seems the negative feedback got to the company and they felt the need to explain themselves
i mean, several sources now said the plan is to release it in january. it HAS to come at some point. otherwise its not looking good and that would be huge, if the tour wouldnt come to fruition
