The Dagger GT has not been cancelled. You'd obviously need a lot of testing for a 300 mph car. So it's kinda okay to have just these renders- remember the Veyron, even with VW at the helm.
The production of the Dagger GT was scheduled for 2011.
The Veyron was presented in 1999 as a study model (already is something more than a render

)
The start of production was subsequently decided, between the announcement and the working prototype have been less than 24 months, the rest was to make perfect the project, an ambitious project, with an "infinite" budget and the obstinacy of Piëch... about the Dagger GT we have only theoretical numbers and ultra ambitious performance goal.
Also, I agree with eran0004, even from the renders you see the seriousness of a project...
I started this discussion because I think that Gran Turismo in the first place has to deal with the TRUE car manufacturers that currently have proven their worth (Koenigsegg, Noble, Gumpert, Ariel, Hennessey, Ascari, BAC etc. etc.)
