GameEx have recently revealed plans to release a new Quadratum to the public some time this Summer.
They claim the new console will not be a sequel to the Quadratum, nor will it be continuing the Quadratum line. It will simply just be a Cartridge Player for people with left-over Quadratum Cartridges to play their games on an Official console.
"This is just us being friendly to the community. We are not continuing the Quadratum line - it will remain Discontinued and Unsupported."
They claim the new Quadratum will be called 'Quadratum Ludio' (Ludio means 'Player' in Latin).
