While Apple still has never confirmed the iWatch's existence (or anything close to to a plan for it) analysts everywhere believe it will launch this fall or winter to mega sales.

Last week, Ming-Chi Kuo, an Apple analyst with a very reliable track record, said he believes a production issue is affecting the iWatch launch date. Kuo believes the smartwatch will not go on sale until late December, missing the holiday sales boom entirely. However, a report from Morgan Stanley shows more market optimism for the device.

Analysts at Morgan Stanley believe the watch will sell for $300, with about a 40-to-50 percent profit margin. They estimate 30-to-60 million iWatches will be sold within the first year of availability. In June, UBS analyst Steven Milunovich also predicted a $300 selling price. However, his sales predictions differed. UBS estimated 21 million units would sell in the 2015 fiscal year and 36 million in 2016.

Morgan Stanley came to their 30-to-60 million sales conclusion by studying brand loyalty and the sales trajectory of iPhone and the iPad. The 12-month price target for Apple stock has been raised at Morgan Stanley, from $99 per share to $132. The low end is $74.
