UPDATE: I've had two different people email me to confirm this is in fact the trailer for Need For Speed: Undercover. One's a tester, the other was involved in its production. The trailer says it's coming out Nov. 18.
Also in the trailer, you can see the lovely Christina Milian, who has been rumoured to be the latest NFS babe for some time. The trailer also points you to a website — Which Road to Take — which features a video screen of a police interrogation gone to the dogs. Click on the video's hotspots and you can see other teases about the game's story. Many readers have pointed out that the timestamp on the video always reads 08.20.08 — could that be the "official" reveal date? If so, someone seriously broke their NDA by getting this trailer out.
The fact that French-language Jeuxgames has it, and none of the other major video sites have put it up yet, is strange. My guess is they don't want to run afoul of NDA issues. Who knows. But it's legit.
