Arm Announces Cortex-A78, Cortex-X Custom

Lets hope that Qualcomm and Mediatek make a laptop SoC using 8 x cortex X1 cores.

Not really, for battery longevity in idle (or occasional load) mode, I would want also 2x A53 cores.

If the marketing is true, performance/power-efficiency sounds really good! However... nothing is mentioned about security improvements.

I'm going to assume the Cortex-A78 is still vulnerable to side channel attacks just like the "Cortex-R7, Cortex-R8, Cortex-A8, Cortex-A9, Cortex-A15, Cortex-A17, Cortex-A57, Cortex-A72, Cortex-A73 and ARM Cortex-A75 cores". These ARM cores are designed for mobile, security should be a priority not an after though nor an elephant in the room.

Actually, in mobile space it doesn't matter that much,... There are worse security vulnerabilities in OS, and you should use applications you trust, anyway. For server/cloud side, where there's lots of virtualization (or containers), security against side channel attacks is more important.

Probably still more secure than processors from Intel and AMD because ARMv8 is such an effective architecture (unlike the shitty x86 architecture) so it doesn't even need symmetric multithreading (SMT) aka HyperThreading, so it doesn't suffer from all those Meltdown, Spectre, etc vulnerabilities.
