thats neat , even though people said its not up to them to decide , i hope they have G27 support for it!

We'll know in couple of months time.

I hope they include 1080p at least for the vertical resolution.

Still haven't got a new tear free 1080p racing experience since ridge racer 7.

Maybe turn 10 can deliver

I suggest investing in a good PC.

Before FM3 came out there was a list of features they were working on that had to be cut due to time constraints, a lot of this stuff was on that list so it's no surprise to see them hinted at for FM4.

I actually don't think all the features will listed will be in the final product cause most of the time features get cut in games.

Fingers crossed anyways though lol.

they can't support g27, it's a hardware incompatibility issue.

Not exactly true, Logitech can do it if they want to.  So far they haven't.

Fanatec has made wheels that work just fine on both the Xbox and the PS3 using both standards.

its good they are adding more features this time, just been playing fm3 and its just time trial or campain. theres nothing really else to play on there, but if it includes night races and rally it will make it more interesting.
