1) No you will not get that update. Flash Charts was a completely different technology and it has been discontinued for a few years now.
2) Since you owned UE (any version) you will get UE4 automatically
3) You will not get Form Builder but you will get the most recent version of validation toolkit, which we will continue to support and make dot releases to ensure it continues to work.
4) You will not get Site Assist pro (or Site Sculptor actually since we don't even have site assist pro any more)
