1. This was prior to the firing of James Gunn which now im concerned about the direction of the Cosmic Universe. Gunn was supposed to be the head of that and with his firing i feel like that entire idea is now in turmoil. Also, with the addition of Fantastic Four and Xmen do they really need to go down this road now? The Eternal's will obviously take place in outer space but I've heard rumblings that is setting up the Xmen to make their debut.
2. Spidey has been my favorite character since i was a kid but this also worries me now. Due to the success of Venom I have a strong feeling they may pull Spiderman out of the MCU to put into the Venom-Verse (Morbius already confirmed as the next movie). I really REALLY want a 3rd MCU spiderman film so hopefully they don't do what you said and screw up the timelines/universes to badly in Phase 4.
Sidenote CW Shows are Awesome, much better than the DCEU. I've seen Aquaman... not great.
I really don't think they are going to pull spidey out of the MCU for the next phase. I think he has too much kid appeal and can make Disney a lot of money and I don't think Disney wants Venom in their kid bubble just like they deff don't want Deadpool in there. Imagine him running around disney. That would be a great meet and greet. lol
I'm excited though to see the x-men hopefully pulled in more into the MCU.
By the time all this mainstreams into the Florida park I'll prob be an old old man and my kids will be grown up.
(The CW shows are awesome. I wish that Gotham was part of that universe from the beginning even though it is a great show on it's own. I'm sad to see that one end this year. Not really looking forward to aquaman. I'll admit I did like Suiside Squad mainly cause the music improved the movie)
Sorry I went off topic a bit.
