The only one back in December was announced before they had their 12 days of Christmas sales, so a couple of weeks prior, I guess. Haven't seen one since, but would like one since I need to buy some OP giraffe camo-
As I recall it there are more 2xSC events over the year and just a couple of 3xSC events. Someone who has played SOE games longer can correct me if I'm mistaken.
someone mentioned quarterly, so we'll see if any info gets leaked. i myself am ready to spend some bucks.
