I kind of want to see them upgrade the engine for 7.0. Don't get me wrong, They have done a phenominal job with the game so far, But I'm pretty sure they've hit the limit on how far they can push this engine.

I'm not saying to rip the engine out and port to a whole new engine. Just a version upgrade to the existing one that is now 10 years old.

Upgrading the engine would probably give them a lot more freedom on improving a whole range of limited things.
