We had previously seen a dark and light variant of the box art that will accompany Windows 8 when it launches and now we have a few more images to paint the complete picture. The images you see are representative of what the box art will look like when it hits retail shelves and there are quite a few variations among them.
Something new contained in these leaked images is the "Pro Pack", whose box art was not previously leaked. We can also now see that the "Pro Pack" will include Media Center but it will only include a serial key, no disc. This package is likely an upgrade only for those who already have Windows 8 and sticks with the announcement by Microsoft that Media Center will be a bolt on application
It won't be too much longer until Microsoft officially unveils the box art as Windows 8 is slated to ship on October 26th. In addition to the launch date, Microsoft has also announced an event on October 25th, likely a massive party to kick-off the sales of their next generation OS, Windows 8 and Windows RT.
