When Disney took over the Marvel Cinematic Universe they had to take with the adopted stepchild Deadpool and in 2024, we get to see what Disney does to, well, Disneyfy the character.
Deadpool is part of the MCU, sort of. This year, Deadpool 3 will see Ryan Reynolds titular character be joined by Hugh Jackman's Wolverine for a massive crossover that could have huge ramifications for future films within the edge of the film universe.
Deadpool is lude, crude, rude, disgusting, and as far off the PG-13 spectrum as you can get without diving into the arena of adult cinema. The previous installments have all been rated "R" and despite a PG released version, D3 is going to hit theaters with all the "R" ratings you can handle.
There is no way that Deadpool can't continue its raunch trends. If they don't, fans will run in droves away from the franchise and crucify Disney for sticking their hands into the franchise.
This is going to be a very interesting test for the House of Mouse. A strong showing from Deadpool could open the doors for more adult-oriented fare in the future. Disney's PG-13 ceiling could be shattered allowing the company to produce films that are directed completely at an adult audience without "family" attached to it.
Disney has strayed away from these kinds of films in the past but they couldn't get around this property when they took over Fox Studios that included fringe characters that were part of both Fox and Marvel, including the X-Men.
Now, Deadpool could be one of the hottest properties for Disney. It's unlikely that we see a 4th film from the franchise simply because another sequel would be a long shot either way but again, opening new doors could open a new world for Disney in multiple areas.
2024 will see the release of Inside Out 2, Mustafa: The Lion King, and Deadpool will be the 3rd big release. It will be interesting to see how it measures up.
