Whats up with the upcoming Battlefield 5

A next Battlefield game is inevitable!
But the rumours are cooking.
I think, that it won't be another modern warfare title.
It would be a pretty safe bet, but the factor, that probably kills it is,
that they invested a lot of work/time/money in BF4.
I mean, free DLC, free maintnance and the community test environment?
That's time consuming! They even added high server tick rate to it!
They could have used BF4 as a beta for BF5, but even IF, the setting would be different.
Many big Youtubers (channel not body size) have covered this topic.
I can recommend the videos by jackfrags!
So where could you fit the features into, that made the Battlefield series so popular?

Battlefield Hardline showed us, that this won't work with a bankrobber/police theme.

Do you have any good ideas?
You know where to find me :-p
