The delay was caused by an issue with stagger escapes (a.k.a. slow escapes) during Criticals that was discovered in the Ver. 1.03 update for PS3 only after it had been released. The corrected patch will be released for both Xbox 360 and PS3 sometime during February, with Xbox 360 owners also being able to pick up the delayed Hotties Swimwear DLC and free Zack Island stage on the same day.
