Andy Digital provided some more information on the upcoming VRInsight overhead in the iFly737 member forums. Since these aren't accessible if you don't own the iFly, you might like to look at the information file he kindly provided at

The unit is not full size, and apparently is expected to retail for around 1500 euros, which makes it about half the price of the nearest similar full size product.
