Meizu chief Jack Wong in comments has alluded to first details of a sequel for the M9. The informally named M9II would move up to a four-inch screen that would run at least 640x960 "or better," he said. Comments plucked by Shanzhaiji from the official Meizu boards also had the new phone making a hop to a dual-core ARM Cortex-A9 processor, 1GB each for EAM and ROM, and a camera with a backside-illuminated CMOS sensor.
