Mac OS X 10.6.5 and iTunes 10.1 to Launch on Wednesday? iOS 4.2 on Friday?

MacStories’s source close with AT&T claims that new iOS 4.2 will be released on Friday at 10 a.m. Mac OS X 10.6.5 completed and waiting for launch.  iTunes 10.1 was ready 3 weeks ago - likely after the release of beta 2 to developers. Both updates should be released on Wednesday. iOS 4.2 will require iTunes 10.1 to be installed and  will bring AirPrint and AirPlay to the iPhone, iPod touch and iPad. But Mac users need Mac OS X 10.6.5 to share a printer with an iOS device, while Windows users will access a printer through iTunes 10.1.
