What's entirely a rumor is the concept that you'll be able to get old-fashion FP once FP+ goes live.
We know FP+ is replacing FP and they intend to do away with FP entirely.
When you say 'We know FP+ is replacing FP' where are you getting that information? Are you making an assumption? or do you really know? If you really know that this is happening could you please note your source, becuase I have not hear that this is happening... just rumors.
