In October last year, Arm's public line was
Last week, Arm announced the new A510 and A710 to replace the A5x and A7x. The little A510 (with a new architecture) is 64 bit only already, and the A710 supports A64, A32 and T32 ISAs.
So what's going on?
Starting with Arm’s 2022 IP, all future Cortex-A “big” cores will only support 64-bit.Given the overview nature of the press release, that heavily implied that the "little" cores would still support 32 bit for a while.

So what's going on?
- Did Arm decide to pull forward end of support for 32 bit, and just not enable it for the A510?
- Is the A510 out sooner than expected? Does that explain why its performance is underwhelming (they've got it working, but not all features are enabled yet)?
- Was there an ARM v9 version of the A55 they decided not to release?
- Are Arm expecting to add 32 bit support to the A510's successor next year, while they remove it from the A710's successor, so that some cores in a asymmetric multi-core chip support 32 bit, but which ones can vary?
