Actually knowing with reasonable certainty you'll get a system at launch.
Just not a common practice in the US for online stores to sell merchandise before they have an agreement with a supplier I guess; not that all pre-orders are always fulfilled on time, because shit happens, but the idea is that what you are buying is an item in their stock based on a deal they have with a supplier.. not a product they hope to get in stock but aren't sure how many they'll be receiving so you never know.
A manager of Sony who's been harassed by me for months prior to PS4 launch had to wake me up at around 9am and in 17 minutes I was there to pick the first PS4 in the region.
