Heck, you always need take leaked specs with a grain of salt, if not a whole shaker of salt, a lime, and a shot of tequila. I think your down-vote was a bit reactionary.
Those leaked specs have been on the pdadb for at least 9 months even though the device was only just officially announced during CES this week. I think the verizon iphone specs have been up there since shortly before (March 2010) the release of the iPhone 4 (June 2010), hence the iOS version it was claimed to be running (during the end of development/prototyping). The first "preview" of iOS 4.x was in April 2010.
Similar was true for Droid2 and Droid2-Global specs being available 9-12 months prior to device releases/announcements. In both those cases, the leaked specs matched up very well with the eventually released products.
Even when a device is "finished" (hardware engineering-wise) the lead times for manufacturing ramp-up and marketing build-up can be many months.
