Lately the Checkered Past block on Adult Swim has been playing it too safe and not taking enough risks by sticking to the same handful of shows and not having any major expansions or block debuts. What makes the future of the block more uncertain is the block losing Fridays to Toonami Rewind, however I believe Checkered Past will stick around for a while because of the unprecedented high ratings. Also Samurai Jack never even got a chance and only lasted a few weeks.
Not just that, MeTV Toons has absolutely NO plans whatsoever to air classic Cartoon Network shows in the foreseeable future, it ever. This gives Checkered Past an even better reason to just go all out rather than stifle the block. In other news, Adult Swim plans to further expand internationally, primarily in Europe.
