Here are some of the details he provided:
- minimum: 2.8GHz, 512mb Ram,Geforce6
- for high details: 3-4GHz, 1Gb Ram, Nvidia 6800GT/ultra or 7800GT/GTX SLI
- Dual-core Processor use: Multi-Threading is supported and should provide much better performance.
- 64 Bit version available with better textures
- Renderers: Shader-3.0, Fallback-Mode for Shader 2.0 maybe a dx8 renderer.
- HDR: yes
- physics: Novodex-Physik-Engine.
- Ageias PhysX Processor supported.

First, there are some faults in the translation:

Beyond Unreal:  minimum: 2.8GHz, 512mb Ram,Geforce6  ; for high details: 3-4GHz, 1Gb Ram, Nvidia 6800GT/ultra or 7800GT/GTX SLI
PCGH: required hardware for highest in-game detail including 4x FSAA and 8:1 AF: 3-4GHz, 1Gb Ram, Nvidia 6800GT/ultra or 7800GT/GTX SLI

Beyond Unreal: 64 Bit version available with better textures
PCGH:  Improvements with the 64 Bit version: Possibility to adress more textures, vertices and levels

Second, as I clarified in a seperate e-mail with Mark Rein, we have some misunderstanding in the term "minimum specs". We mean "minimum specs for high in game detail" which is not the same as bare "minimum specs" so that the game runs at all.
