Sony SGP771 has just leaked and this tablet seems to be Sony’s 2015 flagship slate. The product was spotted on Postel, which is the Indonesian regulatory authority, or their FCC, if you want. The proof is below:

Sony-SGP771

This model may or may not come at MWC 2015 and we’re cautious about such statements, since even the Xperia Z4 is said to skip MWC, according to some rumors. Just a quick reminder of what the codenames thrown around for Xperia Tablets are. We’ve got the SGP3XX as the Xperia Tablet Z from 2013 and the SGP5XX as the Xperia Z2 Tablet in 2014. It makes sense for the SGP7XX to be the Xperia Z4 Tablet, or whatever name Sony decides to use for it.

The two models above were 10 inchers, but Sony also released the 8 inch Xperia Z3 Tablet compact last year, with the model number SGP6XX. Rumors have been saying that Sony may increase diagonal to as high as 12 inches this year, but let’s not get ahead of ourselves. We’ll wait further leaks over the next few days…
