Holic will be coming, don't worry.
We used to release Holic at the same rate as Tsubasa when in fact CLAMP released Tsubasa at a slightly faster rate... this resulted in Holic getting a little too far ahead of itself (the series are interconnected, after all), and to avoid releasing chapters that contained spoilers of future Tsubasa chapters, we have been focusing on Tsubasa in order to get the two back in sync with each other. After this is done, we will monitor our release rates so it doesn't happen again.
