Apparently, details of how this new Mac Publications merger will work is still very much in flux. How the two staffs will be combined, how the unified web site will look, and more - are still unknowns. In any case, the first issue or two of the new Macworld is likely to be a somewhat crude grafting. With the first issue already due out in a month, there won't be time for the ultimate format to be implemented. MacWEEK should continue pretty much unchanged.
As previously reported, MacUser and Macworld will be merging into one magaizne to be called Macworld. The MacUser/MacWEEK booth was distributing copies of Macworld magazine (along with MacUser and MacWEEK) - a strange sight. And given that the show issue of MacUser is the last issue the magazine will print, it is not surprising that the booth was a bit on the quiet side.
