I've maintained for a long time now that the scenery and lighting changes in XP10 would be a huge leap forward. My 4yr old rig isn't capable of pushing XP10 to its limits, but there are a few videos out there that start to show what XP10 is capable of delivering. If you guys find any others, please post them, but this is a good one I just found showing the night lighting:

I'll post more as I encounter them. Once I have a decent rig, I hope to put together some pretty compelling clips myself
Edit: here's another showing the action on the roads in more detail:
