Raspberry Pi are on a first come first served basis, unless you have a confirmed pre-order or a register of interest somewhere at the beginning of the month you will be at least in 200,000th position just at RS (growing at a rate of 10 a minute, and that was 3 days ago.) Don't know Farnell's position, but you'll be looking at end of May/Jun.
