You can upgrade, it just won't migrate your programs - only your data.

As far as I know you should be able to use a 64bit upgrade copy to go from 32bit to 64bit even if it's technically a clean install. Either way I'll be going to 64bit with Win8, if I have to pay a bit more then I'll just swing for an OEM copy.
You guys don't get my point: when you run the WindowsUpgradeAssistant.exe, it downloads the same version as the running OS, no choice to select a x64 if you are running a x86
Actually you can try out the UpgradeAssistant for WRP to have an idea, the main difference is that for the RTM version, after it check that your machine(and OS) is eligible for upgrade, it will direct you to the payment page, the other procedures are basically the same.
So...that's what I said, if you want to have a win8 x64, you need to run the WindowsUpgradeAssistant.exe in a XP/Vista/Win7 x64, then you will download a win8 x64.
