Yeah I'm really looking forward to Beyond. Also looking forward to Justice League and Unlimited.
Lol, sorry.
However, I'm working on one and I'm pretty confident in it so far.
I'm about halfway done with Batman - TAS and a quarter done with Superman - TAS. I've also got about 10% of all the DCAU spin off comics ordered, and all the video games at least tentatively placed.
Once it's done, my DCAU timeline will be the most extensive on the internet, including all series (and all episodes), all four films, the two web series (Gotham Girls and Lobo), the dozen or so different comic book ongoings and all the various one-shots/annuals/mini-series, all canon video games (hence Gotham City Racer won't be included since there's no storyline really), etc.
It will be several months at least, possibly as much as 6 months total before it's all done, but it'll be all-encompassing. I'm also making an attempt to keep the episodes in as close to the order they're available on the DVDs on, though some have to be reordered, at least for Batman-TAS.
Everything is color (between the different series) and font (between the different types of entries: episodes, movies, comics, video games, etc) coded as my other timelines are.
The only thing I'm not including are the several novels based on Batman-TAS, but that's only because they adapt episodes already on the timeline, but also apparently change some aspects of those episodes.
