Ehh, it's the same cycle every time. We all get excited for WWDC, it comes around, we watch it, everyone's disappointed as 'didn't feel better than last year' then slowly as products and update details come out we get excited again and so on and so forth. Rinse. Repeat. Every. Year.
Part of that is that people buy into every single rumor and believe it to be fact. It seems many don't understand what the word "rumor" means. They get upset at Apple when they don't announce a rumored product, as if Apple actually promised them they would release anything rumored.
If you don't fall for the fallacy of rumors, you won't be let down and will be much happier with the things announced.
