I don't think there's going to be much, and I'd say any, confusion.
Firstly Windows 8 RT is only going to be pre-installed and only on ARM devices. So you can't decide to buy it at all.
All home PCs and consumer laptops people will have Windows 8 installed already. Therefore people won't need to make a decision.
Businesses will be able to use Window 8 or the Pro version if they require the more advanced encrpytion or domain management features. (I can also see some high end business laptops having this installed.)
Enterprise users will have their computer installed for them with the Enterprise SKU.
So really there will be no confusion on the users side, the most complicated choice of the whole lot will be for small businesses trying to decide between the normal or Pro version, but I'm sure there will be an upgrade path.
