Sundance(SDL) did the same thing last week and enjoyed a 20% rise from memory. I guess it just depends on the size of the upgrade. Atlas are possibly also trying to prevent the sp from being affected by leaking of the news, which demonstrates their coporate responsibility. That said, i hope they dont release the info at 3.50pm as they have done twice in the past...
