If you're interested in the underlying technology of flex there's some reinvent talks from last year on YouTube where they acknowledge it's based on VM live migration which is I think the first public reference to AWS using migration in their products.

I suspect the burstable types were always priced too cheaply and were more about attracting the cheap market segment which they don't need now in the days of AI money.

Burstable pricing gets complex quick when adding in the option to burst to full usage. Flex seems a lot simpler which is great.
