I was reading about this in edge the other day on lunch.
there releasing 3/4 updates over the course of the year i think.
one coming soon which will add a few new races etc, 1 with nightime + motorbikes and some other game modes, ive seen a screenshot with planes ???? (they were sure this was going to get released or not just soemthing some dev had done for a giggle) and finally another island. i think the 1st update was going to be free but after that small charge.
also the motorbikes will not crash burnout style, they will just hit things and scrape etc but they will not go all slo mo and crash.
all in all what i read makes me want to keep hold of the game.
