While it was assumed that the rejection was attached to THQ’s financial issues, chief technical officer Oles Shishkovtsov stated that wasn’t the case at all. The Wii U, simply put, was not up to the task.
According to Shishkovtsov in an interview, ”Wii U has a horrible, slow CPU.”
Developer 4A Games’ Huw Beynon also noted, “We had an early look at it, we thought we could probably do it, but in terms of the impact we would make on the overall quality of the game - potentially to its detriment - we just figured it wasn’t worth pursuing at this time. It’s something we might return to. I really couldn’t make any promises, though.”
“We had an initial look at the Wii U, but given the size of the team and compared to where we were last time (developing for PC and Xbox 360)) just developing for the PlayStation 3 is a significant addition.”
Metro: Last Light is due to be released in March 2013.
