It is Divinity 2: Developer's Cut... but I've caught myself typing Director's Cut a couple times (a lot more movies have 'cut' versions than games).
Anyone who bought FoV or DKS from the Vault should already have D2:DC added to their games list.
Email Larian (support@larian.com) with the SecuROM key for the PC retail version of D2:ED or DKS to get a voucher for D2:DC from the Larian Vault.
