shame if the implication is that this is only the Xperia 10 (with its A53 low power cores) and not also including the 10 Plus (with its mix of high power and low power cores).

as it would suggest that jolla are struggling with the resources to move beyond the cheap and slow A53 Arm core CPU's (particularly as A53 has now been replaced by A55 in all new SoC designs).
