1. How did Neo-Umbrella came to be and what is it exactly.
2. Who is behind Neo-Umbrella.
3. What are the Ustanaks origins, for example: Where it was created, who created it, when, exactly why (not just to kill Jake) it would've been nice to see a cutscene having to do with all of this.
4.Origins, backstory, how it came to be or anything related to the, "Family" that Simmons was head of like said before.
5.Jake? We'll get back to him...
6.How did Simmons get the necessary "stuff" from Ada to clone her.
7. What was the REAL purpose of Carla? NOTE: ( I believe it was stated in the game ) Can anybody clear this up for me, I'm a bit confused.
8. Who and who exactly created the C-Virus and why, and how?
9.What happened to Sheva? NOTE: ( That was a joke ) The real question is what happened to everyone else...
10.How did Adam the "president" at the time, exactly get infected by Neo-Umbrella?
11.Seriously... We need to know more about Ada and her true intentions. MORE!
12.What did become of Alex Wesker?
There's more but these are a few...
I don't want be bitching... BUT they could've at least had cutscenes having to do with most of these plot holes instead of cutscenes that have ABSOLUTELY nothing to do with the story.
Onto Jake, so....
Everyone who's beat all 4 campaigns and has seen the final cutscene having to do with Jake.
At the end he's seen helping a child fight off some "Napads" which clearly shows he's going to be helping fight bioterrorism.
I believe, well it's pretty safe to say we will be seeing Jake for RE7 because of that final cutscene and it pretty much gives it away.
IDK what capcom was doing but i guess they didn't want to reveal to much in RE6, and im guessing in RE7 most of these questions were asking ourselves will be answered.
I believe RE7 will revolve around Jake and him fighting bioterrorism and him trying to find more about his "Father" - Wesker which will eventually lead himself into trying to take down Neo-Umbrella and possibly meet some old faces that will eventually appear. I don't want to get too deep into this because i want you guys to add more to this and offer your own theories... so yea carry on ^-^
ONE FINAL THING...
Neo-Umbrella's Leader i believe was Carla because they basically dissed Simmons, and now they're both dead. So now there's no leader.
And i believe in RE7 they will reveal the NEW leader, and for someone to control Neo-Umbrella and take charge they would have to be someone really really important someone vital to their success like Oswell or other important figures that took part of or in Umbrella. I could possibly be Alex Wesker you know? The last surviving Wesker child, because everything about Wesker and EVERYTHING having to do with him will be revealed, meaning all those plot holes and secrets we didn't know.
I agree with a lot of what you said, but I think some of those plot holes were already filled. Like Ustanaks origins were briefly explained in some of the files you can get from serpent emblems. They don't go into too much detail, but they do explain some things. Also, the way I saw it, the Family and Neo-Umbrella were completely seperate. Simmons was a part of the Family, but Carla hated him to the point of forming Neo-Umbrella to fight the Family and destroy the world.
As for your theories on the future, I certainly hope they go in that sort of story direction. I don't see the point in mentioning Alex Wesker in RE5 if they're not going to capitalize on him. Also, if they do keep Neo-Umbrella around, then I too am curious to see who the new leader will be. If Alex Wesker does step in to fill that role, then it would be extremely interesting to see how he interacts with Jake. I can only imagine the intense psychological conversations they might have!
Like, you said, it doesn't seem like Capcom wanted to reveal much with RE6. I think/hope they did this on purpose to keep the story open-ended. If so, then it's a good idea, because now they have lots of directions they can go in, and still have opportunities to fill in those story details that were left out of RE6.
