William Blair said its channel checks indicate its Q3 revenue estimate for Research in Motion of $2.5B, which is $130M below the consensus, is at risk. The firm's checks across North America continue to suggest RIM's issues have been compounded by the company's hardware lagging the competition. The firm says BlackBerry devices remain an afterthought in the consumer market. However, William Blair notes RIM's Q3 results next Thursday, November 20, may not matter as investors await the launch of BlackBerry 10 in January. The firm has a Market Perform rating on the stock.
