I've read alot of people have pre-ordered 2-3 systems just to be sure at getting a system on launch day. Im worried people won't let the other shops know quickly, that they have already got a system. the other places will hold onto there pre-orders for a few days, taking systems away from people who want to buy them on the day. I think if you were pre-ordering from somewhere you should have been made to be commited to the order. It should have been £50 to pre-order, and that comes off the final price.
