Seems quite good, I like the game engine and control better than Race Driver but there is a lot of lag but that might be because I'm running it an old M3 CF. Seems to be like that with some 3D EA games.
I'm surprised that they didn't show any screens or anything of this as I don't see any problems with the way it looks aside from the car models.
Much better than the other DS NFS games which were pretty shitty but to be honest I prefer the Asphalt GT 1 & 2 to this (AGT 3 is coming to DS soon). Not a bad racer at all.
