I think you need to take a break from the forums until you get your watch. Your bitterness in not getting it when you wanted it is showing in your posts.
Don't be surprised if a significant update doesn't come out until around or after WWDC. If anything they'll roll out fixes for debilitating issues but no major changes until 3-6 months.
Every one of their OS's sees a major upgrade annually with 2-4 minor patches throughout the year. I'd expect the same for Watch OS.
Apple said that by launch communication speeds in third-party apps would be improved, does anyone have a pre-launch watch so they can see if the OS version is different?
Why bother wondering? The first iPhone came out June 2007, and they are still releasing new versions and update. You're really trying to find problems to talk about. Go enjoy the watch.
