Would a 2014 iWatch be the first Post-Steve iOS device?

Obviously this is just pure speculation, but everyone is curious if Apple can continue to innovate and push the boundaries in the Tim Cook era of Apple.

Steve was pretty sick in 2010, and 2011 he resigned from Apple. How long would it take for Apple to conceive and design something Ike an iWatch? Is it possible that they could have started this project in late 2011, developed and refined it through 2012, and 2013, with a 2014 release?

This is just speculation, but any insight would be appreciated. Thanks.
