Serious: How will GTA VI be an upgrade over GTA V

Things that come to mind:

1. Graphics

2. Better AI

3. Better destruction physics

4. Larger crowds

5. Larger map

I can't think of anything else.

Can any of you think of anything else that would make GTA VI better? I am trying to figure out what Rockstar could do that would make GTA VI an actually appealing game in today's market.
