This is still Codemasters, and this is only the first real info on the game. CM is good at only showing what they want and keeping the rest quiet.
I don't think the In-car cam is gone FOR GOOD, at release yes but we live in an age where everything can be modified with downloads, so what aside from an angry mob would keep them from eventually releasing them as DLC or an update similar to GT5's 2.0 Update.
Race Cars? It's not a question of ARE there race cars, but how far you want to go with it. LMPs? Maybe not, and if EA has it's way there won't be a 911 at all, but almost all the Pro Street/Pro Muscle cars real world counterparts were likely modified for racing, if only a roll cage and tuning. But as I said three lines ago, DLC is a bigger option than it was in 2008, so don't fret too much unless like me you're cheap.
Someone said something about the bloom and filters? I'll put $5 says they're back. I must admit one thing, last time I really played Grid, I had a standard definition TV, and sudden light changes (Long Beach specifically) gave my eyes hell. I need to play again on my HDTV so I can see if it's the game or the TV.
Doesn't appear the livery system from Grid 1 is returning (yet), which is a bummer but it could be worse.
All I've got for now, still happy it hasn't been killed off in favor of three more Dirt spinoffs.
