EDIT. We have mistakenly indicated it's Milviz that's developing the G1000. Milviz contacted us and we need to make a corretion: NavStax is the company doing the G1000.
Milviz surprised the community today at FSElite's stream where they showed the development of the G1000 which will make it into an helicopter.
The team has confirmed, on the chat, that they are, indeed, working on a new version of the Bell 407, which would obviously be the 407GXi. They also indicated they are working on new flight dynamics (this was not actually something new since there were some contacts made with us some time ago).
Prepar3D users will be pleased to know this new model will enter their sim.
We'll keep you all updated as we get more information.
