Ahead of schedule: the Sony Xperia XZ is already available in Taiwan
Well, it seems Taiwan beat everybody to the punch, as it's reported that the aforementioned Xperia XZ Dual has gone on sale in the country today. It costs the equivalent of $730 and probably comes with 64 GB of internal storage — like the Dual that is about to launch in India.
No need to rush to 3rd party reseller websites that import from Asia, though. The new Xperias will be over to the West in just a couple of days. Are you buying an Xperia XZ on day 1?
