We keep hearing about Apple supposedly knocking together some kind of online TV service, and the Wall Street Journal is the latest source to offer a few more tidbits on the apparent project.

The news outlet says the tech titan is moving towards the launch of a “slimmed-down bundle” of about 25 prominent channels from various networks, among them ABC, CBS, and Fox. ESPN and FX may also be included. It’s expected that Apple will charge around $30 to $40 a month for the service, significantly more than the similar $20-a-month Sling TV service from Dish Network.

Apple’s online service is expected to launch in September following an announcement in June, people familiar with the plans told the Journal, with subscribers able to watch shows on iPhones, iPads, iPod Touch models, and Apple TV set-top boxes.

Unsurprisingly, the complexity of the deals needed to launch an online TV service like this means Apple’s been hitting a few bumps along the way. For example, talks with NBCUniversal are yet to begin, apparently because of a dispute between Apple and NBCUniversal’s parent company, cable giant Comcast. The pair were in talks last year about a possible TV service but fell out when Apple reportedly accused Comcast of stringing it along while it worked on its own X1 cable box.

Without NBCUniversal on board, channels such as Bravo and USA will be missing from Apple’s service at launch.
