My guess would be no. Although I would like to see an iWatch at the WWDC 2014, I don't think they are going to release one just yet. I think Apple want to fine tune the watch and perfect it before they release it. I also don't think that they would release it at a Developers Conference.
I think we are going to see updates on the Macs, iPods and software, but i don't think we are going to see an iWatch. Nobody knows, I could be totally wrong, but my guess would be no. I guess we will see in 10 days:)
