Johnny's net updated a few days ago with this information but Tackey & Tsubasa will be having a tour this year after all. It will start mid-September and go through early November.
One thing I could not help but notice is that all the venues listed look to be concert halls which kinda surprised me. I'm so used to arenas for these kinds of tours but I'm only kinda surprised because T&T really does seem to have declined in popularity quite a bit over the years and I guess something like this was bound to happen. Though at least they're still together and performing so it's no completely bleak.
Also on a side note TakiCHANel has gone through an overhaul with new features that are available or set to start in the future so make sure to check it out.
