I think they have just taken the available craft from 2048, and not put in the other 5 craft from HD/FURY just to keep the graphics cleaner looking.
There would be a lot of pissed off Icarus & Harimau pilots if those craft weren't made available.....the others .... well they never seemed to get seen much in online racing, maybe Triakis & Mirage in elimination....Assagai, very few used.
