I have seen threads that said the upgrade version would be available for $36.95 up to $39.00. It will be availble from Microsoft as a download and you will be able to upgrade win 7 any version to Win 8 Pro with no data loss. (sso they say). So far I have taken the consumer preversion and upgraded 2 computers from Win7 Home premium and upgraded to Win 8 without any problems.

You have to remember that Win does not have all the apps embedded. You will have to go to the "store" and purchase any apps that you want. Here is a link to the preview. There is also a download now button if you want to get a head start on it for free now. http://windows.microsoft.com/en-US/w...OandO_DL_EN-US
