Calm down dude, the preview is the same as the final build, so it's not different...
Well is that the truth or a assumption?
Cous i have noticed some tiny differences between the preview of GDR3 and the final.
For example the backbutton and the icons who came with the smaller preview-windows.
I remember the store had a music pictogram instead of the shoppingbag, and there where a other view.
Just tiny things, but stil a difference between the Gdr3 preview and the final release.
The mainstream says we getting the preview, because it happend with Gdr3 the same way.
Thats a assumption.
Even that everything looks that way that we are getting a preview on the 2th, its stil not official stated by Microsoft.
But we all hope for the best.
