If it was using IDtech 4, it would probably be out already.
You would think, but you're probably wrong here, and here's why:
1) Human Head worked with 3D Realms on Prey and the game was mildly successful. It did well enough to warrant a sequel, as can be seen.
2) Radar Group (Scott Miller-founded, also the same Miller who is president of 3D Realms) began working with developers to develop concepts worthy of creating games. Radar, however, most likely stumbled onto hard times: Earth No More (Recoil games) was one of their projects, and it is now on indefinite hold due to legal troubles. Prey 2 was on their website as an in-development project as well. Not much was said about it, but we can assume production was in motion.
3) 3D Realms, thanks to the 2K suit, and other issues, obviously had to let go of their staff and sell the Duke IP and game to Gearbox. With Earth No More in turmoil, and obvious financial difficulty, whatever Prey 2 was had to be saved.
4) Bethesda picks up the rights in 2009. idTech 5 is still in development, and with Doom 4 getting started as another internal project, very little support could probably be lent to Prey 2 -- a game already in development by Human Head. As far as I understand the pipeline of development for an id Tech 5 game differs greatly from id Tech 4.
The big thing to realize is that id Tech 4 has semi-support for megatexture technology, and is a VERY competent engine. I wouldn't be concerned at all about the visuals, and, really, if you want to make a killer fps game the time-frame is about correct for them. So, in short, no, it doesn't have to be out already.
