Earlier today, Bethesda released the "PC system requirements" for Wolfenstein: The New Order. Their labeling conventions are a bit askew, however, as while it does say "PC system requirements," these specs are more akin to the recommended specs.
The system requirements are based on the game being a next-gen experience running at 60fps. These are the system requirements to deliver the PC game as it was intended to be experienced.

PC SYSTEM REQUIREMENTS
  • 64-bit Windows 7/Windows 8
  • Intel Core i7 or equivalent AMD
  • 4 GB System RAM
  • 50 GB free HDD space
  • GeForce 460, ATI Radeon HD 6850
  • High Speed Internet Connection
  • Steam account and activation required

So, if you want a solid 60fps experience with all the bells and whistles, you better make sure you have an i7 CPU apparently.

They also mentioned some of the requirements for the console versions of the game, including a four disc Xbox 360 version.
