I think its already been sped up recently. Besides, if you take away the third spin you lose the "aww.. so close/crap" factor. Emotional manipulation is the basis of slots! If the decision is made to speed up the slots again, could you leave a longer time for FG, HB and high tier PvP games? These games take time, and it'd sort of irritate me if my victory was belittled by a super speedy spin.
