Huawei usually releases a slick, camera-centric P device in April and follows it with an improved, more robust Mate device towards the end of the year. Last year saw the P30 Pro introduce a triple-camera setup only for it to be topped with October's Mate 20 Pro, which featured a more powerful processor and a quad-camera setup. Samsung follows a similar schedule with its Galaxy S and Galaxy Note lines. 

The P30 Pro has inherited a similar quad-camera setup and is powered by the same Kirin 980 processor featured in the Mate 20 Pro. No word on how many cameras the Mate 30 will rock -- presumably at least four -- but it'll surely pack a more robust CPU.
