At this point it's pretty much a given that it is coming over. The sedan and coupe are here already (Infiniti G35 sedan and coupe) and Nissan has been pretty posititive about a US release. Also there's a pic on the actual
Nissan site itself. When the site first loads, in the lower right hand corner is the v35 gtr concept that they showed in detroit. Stranger things have happened though, Ford still is unwilling to bring over the Focus RS and GM has been about as bad with the Opel Speedster (sharing the same body as the Lotus Elise that is coming over in 2004). I think they'd have to be fools not to though. The crash tests have to be complete on the frame -- it's the same as the G35 Coupe with different styling.
