Given that it takes a titanic effort to mod airliners to something decent (the A320NX development patches are being issued almost on a daily basis) and no similar initiative that I know of exists on the Boeing side. Given that trusted third-party commercial developers are at least a year away from releasing their products for the MSFS platform, based on their own announcements. I would say that for the next 12 months we are bound to take the Boeing aircraft for what they are, pretty models that are fun for casual flying.
