I also don't remember any significant announcements (P2 key drivers) announced on a Friday. Please point me to that one? All I see are options grants on Fridays and the Aug 16,2013 which was insignificant as indicated by the market reaction. You and I have been doing this long enough to know that companies generally do not release very positive news releases on Fridays. Maybe a halt that carries over to the next week.
MS8/partner announcement and P2 in my mind are monster announcements and will be timed for maximum impact. Especially since they have been a long time coming. But to be honest, I will take it any day of the week at this point.
