Evidently Sony are targeting North America and UK so they are allocating the majority of shipmenets there. In Australia for instance the pre-orders are so high (or the shipmenets are so low?) that it is impossible to get a PS4 until next year.
I can imagine a similar scenario in Europe. In any case considering they are guaranteed to sell over 3 million by the end of the year worldwide, Sony's estimate of 5 million sold by the end of March 2014 in hindsight may even turn out to be a tad pessimistic.
