Users in the UK, France and Spain have already seen them as available
In France, Google is selling the two Android devices at prices that start at only €299 and €399 for the lower capacity Nexus 4 and Nexus 10 models, respectively.
Users in Spain should also be able to grab the two devices, the same as those in other countries where Google announced them as available. Both of them should be released in the US as well in a few hours.
Update: Nexus 4 was sold out in the UK in minutes after being put up for sale.
