Snapdragon 801 processor that powers the Z2 at the moment. Snapdragon 805 is faster, and more oriented towards 4K encoding, decoding and streaming than 801, but Sony might have concluded that these niceties are ahead of their time, as 801 is mighty powerful as it is, while 4K content is not exactly abundant just yet. Judging from the thread replies of the source, Sony might jump straight to Snapdragon 810, which is expected to land in time for the Spring 2015 flagships.This likely means that the Z3 will employ the same
Xperia T3 that was announced yesterday.
Given the line's heritage, the Z3 should also be waterproof, and we are very curious to see how Sony has pulled that off in such an anorexic handset. The Xperia Z3 is expected to be announced after the summer, in September, when it will have to battle the eventual iPhone 6, Note 4, and the HTC One (M8) Prime, all of which are likely to be unveiled around that time.
As for a speculated Z Ultra successor, the source shoots down this rumor, saying that Sony has no plans to release another thin, gigantic handset, that is borderline tablet-y. If you thought the first half of the year to be interesting, the second is shaping up to be even crazier, it seems.
