I saw that there will be some vehicle combat action going on. Will it give it a sort of Jak and Daxter feeling to it? I want to know your guys opinion on this.

I hope so to be honest, I loved Jak and Dexter when I was little. Jak 3 had pretty good vehicle combat for the type of game that it was and it's time, but it was too repetitive. I hope it is much better.

How i've heard it described is like Mario Kart but more badass pickups/powerups

It's like twisted metal and mario kart. But even better
