I'm sure Disney/Marvel is working very hard now, especially with the exiting of James Gunn, to restructure the MCU. I have this feeling there may be no GotG 3. Here's why...
Since Marvel initially wasn't able to recapture cinema rights to The X-Men & F4, cinematically speaking, they had to find replacements. The Inhumans were thrust to the forefront of the comics (pushing the X-Men to the backgorund), and all ancillary media, had their own film on the MCU slate (until it was downgraded to a TV series, that failed after one season).
They also needed a new *family* dynamic to replace the F4. The GotG seemed to fill that need, until of course about 2 months ago. GotG also were thrust to the forefront of Marvel Comics, and all ancillary tie-ins, while the F4 got the shaft.
Now that Gunn & Marvel have officially separated. I just have this feeling. The GotG animated series still has 13 episodes of a 3rd season left to air. If we don't see those in the next couple months, I would take that as a sign, also if we see all GotG comics end abruptly, and a slow reemergence of the F4, that will be a sure sign as well.
Though the Fox/Disney merger has a LOT left to sort out, and I don't think we will see the F4 or X-Men in an MCU film for at least 3-4 years, I believe they are doing some early prepping now, to cast aside their "stand ins", now that they have access to the rest of the main players in Marvel Comics. It's sad, and very petty of Disney, but I've seen it before. Also another sure fire sign is...if in the next year or so, we start to see F4 or any X-Men characters show up in animated series. They could have used them all along, but stopped around 2013-2014, because, ya know, they didn't want to hype the characters of another studio
.
In 2014, the entire MCU slate was revealed through 2019. Of course we know that has changed a little, some dates were shifted. Ant-Man got a sequel, Spider-Man got 2 films, and Inhumans was eliminated. However, now we are approaching the end of what had previously been revealed some 4 years ago.
2019 schedule
February -Captain Marvel
May- Avengers 4
July Spider-Man Far From Home...
and that's it. Sure there are "dates" for 2-3 MCU movies every year until 2022, but nothing more has been revealed. Marvel Studios had no presence at SDCC or NYCC this year. I know Disney has their own show, I guess the next one will be in August of 2019, after Spider-Man FFH comes out. I guess THAT could be their big reveal for the next few years....Still, that would be cutting things kind of close, especially for any films released in early 2020.
There are no more good TV Shows, only ones that haven't disappointed me yet.
