That is quite possibly the most beautiful bird I've ever seen, real or not. As far as features, what'll it have? Autopilots, payload bay, UMmu, etc.? Looks are great, but I want a bit more before switching off the DGIV.
It will have all the features of the XR1 (which are better than the DGIV IMO, but that's another topic entirely). That means:
- Vertical velocity holding autopilot
- Attitude holding autopilot
- Airspeed holding autopilot
- SCRAM engines
- Ummu support
- Oxygen supplies that get depleted
- Damage and failure simulation (ie: you can die, break things, etc...)
- A radiator that actually dissapates heat instead of just looking pretty
- Voices are done by a voice actress instead of a computer
- Temperature display
- All kinds of other nice things that I can't remember.
I don't think that the XR2 will have a payload bay, but the XR5 has a nice big one, and an excellent payload managment system that allows you to put in pretty much anything.
