I think the shadow at the start is the Steckimobile, via process of elimination, 1 being Eric has had to do no real modelling lately, 2, ALL overhead pictures that are meant to show the track, have had the car hidden in Garage or using a secret dev invisible model, 3, I can't see eric doing a new car, or the MRT6 being released which leaves the steckimobile to be the last plausable answer.
