For some domains you will likely need to get a new SLD from a gTLD. For example, a club may need mycoolclub.club in order to remain current or modern. The city of Paris will have a whole new set of TLDs. metro.paris, wine.paris etc... and those would make the related websites look more professional. My startup's technology (simMachines) has been involved in the process of selection of gTLDs and security compliance checks so I can tell you that ICANN has invested a lot in making sure the transition will be safe and fair for everybody.
