This year's Sony Xperia XZ3 has come and gone without 5G but we think it's almost certain that the Xperia XZ4 (or whatever it ends up being called) is going to have the super-fast technology.
"Smartphone innovation has always been at the core of Sony Mobile engineers. design philosophy," said Sony as it recently talked up its heritage of world firsts in smartphone technology.
It made these comments mere days after rival makers OnePlus and Huawei confirmed they were working on 5G phones.
A coincidence? We think not.
In fact, going off what we know already about Sony's commitment to 5G, as well as Sony's track record, it does indeed look like at least one of the company's 2019 phones will feature 5G.
We've already heard a few rumours and hints trickle out: here's everything we know so far about the 5G Sony Xperia phone for 2019.
If it is to release the first 5G phone, potentially with a battery that can last an entire week, then it looks like Sony is going to be launching it before the end of February 2019, which is when the Samsung Galaxy S10 is slated for an unveiling.
