1:08 PM BlackBerry (BBRY -6.1%) adds to this week's losses following critical reports from National Bank and Wedge Partners. NB has slashed its estimates, isn't happy with the delayed U.S. rollout of the Z10 and Q10, thinks cash/share might fall by over $1 in FY14, and foresees a major drop in high-margin services revenue as BB7 subs migrate to BB10 (previous). Wedge says it's receiving signs "U.S. carriers are not optimistic" about Z10 sales, and considers iOS/Android "simply too entrenched" within the country. [Tech, On the Move] Comment!
