Didn’t think the Apple Watch would catch on? Not everyone agrees, especially analysts who study sales projections.

Cupertino is on track to sell 21 million watches and rake in about $8.4 billion in revenue in the first 12 months of the Apple Watch, according to one of the hottest Apple analysts around. Not bad for a company that entered the wearables game late.

An upcoming summit aims to get to the bottom of what is going on with the Apple Watch.

The Glance conference, which describes itself as “the first conference on the business of Apple Watch” is going down in San Francisco next month. It will bring venture capitalists and industry insiders together to try to figure out the wearable.
