Sony Computer Entertainment Europe is responsible for managing and distribution PlayStation games across Australia, New Zealand, Europe, India, Middle East, and South Africa. Due to what Telltale Studios only calls 'unforseen circumstances', the release has been delayed a day for PS3 (November 25th) and two days for PS4 (November 26th). They wrote, "there is a 48 hour delay releasing the PS4 version in SCEE territories."
Thankfully this has already been sorted out, but it is bizarre that Sony is making Telltale wait for an unspecified reason.
