While the Steve Jobs keynote at the WWDC was underwhelming to many, there’s been a lot of interesting related news that’s come out in the last two days:

• Most iPhone apps are going to be free – Piper Jaffray analyst Gene Munster, took some time Monday following Steve Jobs’s opening keynote to chat with 20 Apple developers. He found that 50% of them were in attendance because they plan to focus solely on developing applications for iPhone and iPod touch. “We found the average cost of iPhone apps on the App Store to be $2.29, with 71% being free,” notes Munster. via appleinsider
• The App Store is coming July 11 – in case that wasn’t clear from the keynote, Apple confirmed this Monday. 
• Apple’s App Store could be a $1.2 billion business by next year. In a research note to clients early Wednesday, analyst Gene Munster said his $1 billion market prediction represents the better of a three-case scenario that would add anywhere from 1 to 3% in operating income for Apple by the end of the 2009 calendar year. Munster based this assumption off the adoption rates announced at WWDC for the iPhone’s existing services. “Mobile service adoption rates show that iPhone owners are more sophisticated mobile users, likely a result of both the user profile and the device itself,” the analyst told clients. “The bottom line is that we expect similar adoption of the App Store to other advanced services.” via Digital Daily
• The next version of OS X, Snow Leopard, is losing Power PC support. According to info published by LigicielMac, the Snow Leopard Developer Preview requires an Intel Processor, DVD, 512 MB Ram & 9 GB of disk space. I haven’t seen official confirmation on whether or not the final requirements will match the developer requirements.
