The upcoming Expert Series 3 Embraer Praetor 600 from Working Title/Microsoft will use the Proline Fusion, and being a first party developer/product, I would suspect that means the Proline Fusion suite would become part of the available default avionics for any other aircraft that wanted to use them (which, if true, would roll out in a future AAU, maybe 6, just like the Avidyne stuff rolled out in AAU4)
