Saw this over on NeoGaf

All confirmed tonight on Twitch by Dan.  

Paints and tunes can still be created and used, but painters and tuners are paid according to usage. The game will 'learn' what kind of paints you like and will direct them to you.It was suggested that Drivatar cars (ie AI) will use community paints/liveries.  

Oh, and Dan was unsure about existing wheel support, said he wasn't the best man to ask.  Disappointing news about weather and night, but kudos to Turn 10 for being up front about it now.  

Edit: not sure how true this is, but it was hinted by Dan that all material shaders used in the game can be used to paint the car, eg full brushed aluminium finish, full carbon finish. Maybe leather cars? Sounds daft.  Edit 2: ALL cars are Autovista now. This possibly/probably means a vastly reduced car roster from FM4.

WHAT?!

Why do they refuse to put night driving and weather in their games?! This is maddening!

Uh.... what does paid according to usage mean

I could swear the E3 presentation showed dynamic weather.

They have a contract with Microsoft to have a Forza game out every two years, so either they didn't have enough time or the game is rushed.

When Xbox Two comes out then Forza will be able to handle all that extra stuff. For now its just racing in the daylight.

Can't handle? We have 360 launch games with weather and nightime.

ahh I love weather effects and day/night cycles in racers. It just feels so cool to drive into the sunset xD

well... that's disappointing. Hopefully they release the features in a free DLC or something.

Ugh Forza Horizon had night races... that's a bit lazy.

The roster is still "hundreds of cars". That was said in the trailer.
