TN has always posted a new DLC every 2 weeks: apparently they changed this trend in the recent days with a DLC released every week, but this is just an appearence. Actually they continued to relase an original new DLC pack every 2 weeks, filling the "empty week" with a DLC already relased in the past in exclusive countries (Pop Idol, Swimsuits, Orochi).
Now this kind of DLC is ended if not for Kasumi's ragnarok outfit (TN promised to relase it on Xbox and again on PS3, very likely not free this time). So while I think that surely we will get a DLC pack in this or the next week, it's not impossible getting the Ragnarok outfit or nothing tomorrow.
