The iPod touch post was for the release of the 4th gen Retina Touch. That was released in September 2010.
More importantly, none of these "leaks" are surprises. They've either been confirmed by Apple(the 5 in the announcement), or are for devices that are overdue for a new version-the newest iPod Touch and Nano models were originally released in 2010.
The date in the URLs is for today. Yeah, it's no big surprises on the names and updates. Just thought it was funny that Apple's search indexes on their site provided links to draft status posts.
