It will be more than likely be from Studio 4 with a rejigged version of the Prime Time set with two presentations areas for Bryan Dobson and Miriam O’Callaghan. A third presentation area will be likely from within the RTÉ newsroom or from the election RTÉ staff centre which I think is based in stage 1 at the studio complex. This is usually the presentation area for David McCullagh. This has been the presentation setup for the last general election
I cannot seem them using studio 3 for GE 2020 unless they are planning to transfer one of the presentations area a la Miriam O’Callaghan presenting from The RDS count centre with Bryan Dobson coming from studio 3. We’ll know in 3 weeks 😃
