I think it's because the sells of this sku are too high, and microsoft don't do the necesseries things to fix the problem. In France a lot of people on different forums speak they search arcades sku, and they don't find them.
In Italy they said that:

News su 360: Microsoft distribuirà un po' di console ad inizio Luglio, poi fino all'ultima settimana di Agosto non se ne parla più wink3.gif
La suddivisione dovrebbe essere 65% Arcade 20% Pro e 15% Elite.

Which for me want say that this sku sells the most of the three sku.
When GTA 4 was launch (29 april), prosugno told us this sku was sold out.
And for others countries in Europe, i think it's actually impossible to find easily this sku.
