The Sony SGP771 model number has appeared on the Indonesian Postel Regulatory site. There is a good chance that this will be Sony’s tablet offering for 2015. As a quick reminder, the SGP3XX was the model number for the Xperia Tablet Z (2013), the SGP5XX was the number for the Xperia Z2 Tablet (2014) and therefore it follows that the SGP7XX will be the main tablet for 2015.
All of the above tablets were 10-inch devices, however Sony also released the 8-inch Xperia Z3 Tablet Compact last year which had model number SGP6XX. It remains to be seen what screen size Sony uses for the SGP7XX – there have been rumours that Sony will go bigger than 10-inches this year. We’ll keep you posted with any further developments.
