@leocg I think that flash will not just stop working but Adobe will stop supporting it and will remove all FP download pages. So users that already have it installed would be able to use it.
Now in chromium browsers there is a mechanism for disabling out-dated plugins without actually updating the browser, chrome will use it to disable FP in all versions.
My question above was if Opera will use that mechanism as well to disable FP to all chromium-based Opera versions.
You said probably not. However, I need more certainty in the answer as "probably" is 50/50 chance :), and it is hard do use it as an argument to make a decision.
