They most likely wrote it on the 30th and signed it for the 31st so that when it was time to release the RP, all of the content would be ready to be pushed live, i.e. links, posts, etc. I don't quite understand why you're concerned about the post being dated a day into the future when that simply implies we'll get the release preview today as confirmed by a considerable number of internal sources? Seeing as it's the 31st in the majority of the world by now, with the exceptions of random things in the middle of the Eastern Pacific maybe, the release preview should be here in just a couple more hours. I'd wager that it'd be mid morning when it's released (based on EDT), of course, I have no facts to back that up.

I'd say that Chuck has prepared his post a few days early, signed it in the bottom, along with the date on which it should've been published (May 31 2012) but... published it a day early. When he realized the mistake he deleted the post, so ... I think we'll see that exact same post, on the blog, in 12 hours. But the verge's sources said 31 may... wrong tip ? Or maybe on their private ftp... ?
he posted on 30 May, but he was used to post it today, on 31 May (there are 13:11 of 31 May, so i don't know what is your time.)
you dont understand me, if Chuck Chan post it yesterday so he mean WRP will avaliable today, Then Neowin.net Share the post as confirmed information until about 2 Hours ago. Now Neowin says WRP will Available tomorrow!!! so who's the wrong Neowin.net or Chuck Chan????
Microsoft supports says nothing either. The person on the chat thought I wanted to know information about Windows 98 Consumer Preview.
All are rumors. Nobody confirmed even first of June. Maybe it comes at E3, when Microsoft gives their conference showing off Xbox running special version of Windows.. makes sense though.
with which time zone it will release ? and which date ? to me after 8 hours it will be 10:00 PM 5/31/2012
