I think the issue with splitting the user-base is only an issue when there is a divide in the beginning. That's establishing two separate, independently growing user-bases. If for the first year or two, every user who purchases a PS3 is forced to pick up the 'bundled' harddrive, the precedent will be set by the one userbase that every PS3 will have a harddrive...even though, technically, Sony could introduce another SKU (or revise the one SKU) without a harddrive to allow user's more flexibility with harddrive choices as they are introduced and to cut costs on their end. The precedent of an installed user base all having a harddrive is what's important...not the fact that a harddrive is or isn't included with the system over the entire life of the system.
