Relax bro. It is quite common for them to release hardware at WWDC.
New hardware is also very much needed.
I know that. I've been an Apple customer for over 15 years. But, just ask yourself, what would be the point of releasing hardware at a software developer conference? And when Apple was doing the MacWorld conferences they weren't releasing much hardware at WWDC. Because the releasing new hardware at MacWorld..You might've seen one product like a Mac desktop announced at WWDC.
Also the show lasted two hours. Did you really expect them to keep going on for a couple more hours releasing the hardware? They're only humans. Interesting. Microsoft announces ONE product this year and their customers aren't complaining.
