'Lorem ipsum, etc.' has been standard filler text for a long, long time. Don't read anything into that. This layout is probably the basic framework for the pages to come, but using old data to make sure the layout and links all work properly. The only real work I see here that won't be used later are the spoofs of 'The Bat' that would not take terribly long to produce. The blueprints, on the other hand, would have taken a insane amount of work for an outsider to produce, and quite a large amount of work even for an insider. My feeling is that the prints are real, and this early release of 'The Bat' is a little silt to muddy the water for a few days.
