Also, the site that first reported that Arkane Austin were taking over development duties on Prey 2 are saying that their Prey reboot will be revealed at Bethesda's E3 Conference."All Ive heard is that theyre announcing it at E3! Im not 100% sure, though. I do know its codenamed Danielle and under development at Arkane Austin. And this is a totally new Prey 2 (it might even be called something else now), not the one we saw in 2011 from Human Head."
