The first fall promo for One Chicago's new season is released. While the Law & Order franchise inhabits New York, TV producer Dick Wolf's other successful procedural shows live in the Windy City. Chicago Fire, Chicago PD, and Chicago Med consecutively air during NBC's Wednesday primetime block, with regular three-way crossovers almost every year.Production for all three series has been in full swing for a while now, with the cast members sharing images and videos from their sets. Chicago Fire season 11 behind-the-scenes photos even spoiled season 10's cliffhanger finale. Despite the looming threat, it has already been revealed that both Stella Kidd and Kelly Severide will be safe. Meanwhile, actors from Chicago PD and Chicago Med focus on sharing snaps of them clearly having a great time during filming breaks. These have only made fans more excited for One Chicago's impending return.Related: Chicago Fire Spoilers: How S10's Cliffhanger Ending Can Be SolvedNow, Wolf Entertainment releases the first promotional video for the return of One Chicago this fall. In the clip, each show gets its segment, with the core characters representing their teams. Unfortunately, aside from the marketing shots, the trailer doesn't feature any new footage from Chicago Fire, Chicago PD, and Chicago Med's respective upcoming seasons. Nonetheless, it hypes up the franchise's fans, as evidenced by the comments section. Check out the video below:

Amid the nearing return of One Chicago, however, several behind-the-scenes developments may be putting its run in jeopardy. The biggest one concerns NBC reportedly looking to abandon its 10pm primetime time slot, which means that Chicago PD will either be forced to move days or be canceled entirely. The latter seems too extreme, however, considering that the show remains one of the highest-rated series on the network. But if the company decides to move forward with this change, the One Chicago Wednesday block could end up being dissolved, with each show potentially airing on different days. It's worth noting that this will be the final guaranteed year for Chicago Fire, Chicago PD, and Chicago Med, meaning all series will have to go through re-evaluation for their likely renewals.

It's interesting, however, that despite already filming for a while now, Wolf Entertainment opted not to include any new footage for Chicago Fire season 11, Chicago PD season 10, and Chicago Med season 8. Surely, the One Chicago shows could have submitted even just short snippets of what they have worked on in the last several weeks to kickstart the franchise's marketing campaign. Another thing that's missing from the video is the much-awaited three-way crossover event that many are expecting to return this year. This is especially so since the Law & Order series have confirmed a crossover event with SVU, Organized Crime, and Law & Order.
