One of the primary objectives of NASA's Nancy Grace Roman Space Telescope is to conduct a comprehensive statistical survey of cold exoplanet demographics using gravitational microlensing - requiring not only detection but also characterization of exoplanets. Incorporating Roman's latest technical specifications, we compute updated yield predictions for cold giant planets, based on realistic simulations over a full range of survey designs endorsed by Galactic Bulge Time Domain Survey definition committee. We compare survey architectures based on cadence and exposure-time, science filters, and colour-cadence; exploring how these parameters influence the planetary detection rate and Roman's ability to constrain the physical properties of lens systems, particularly their masses and distances.
