Hola, parece que ya hay precios....
The Nexus 4 will be sold (at least initially) unlocked, supporting some 200 carriers that play by the GSM / HSPA+ rules. It'll be made available in both 8GB and 16GB versions starting November 13 in the US, UK, Canada, Germany, France, Spain and Australia, with pricing set for $299 (8GB) / $349 (16GB). The 16GB version will also be available through T-Mobile for $199, with a 2-year contract.

Aun con conversión 1:1 creo que la versión de 16GB por 350 euros está bastante bien. Y a la venta en apenas 15 días.
Un saludo.
