Gulfstream has new jet coming Oct 4th I can see them bringing in G400 but not G800. G800 will kill G700 sales. Either way bombardier got upper hand on them again by introducing challenger 3500. Expect rollout of an aircraft on Oct 4th Similar to what they did with G500/G600. I think it will be smaller then G450 as G500 is bit larger and Gulfstream needs something bid smaller the G500 to round off their offering. If there is a G800 coming then this is good for bombardier. They haven't launched or set the size of Global 8000. Maybe it will be Global 8500 which will leap frog in range. https://www.flightglobal.com/airframers/report-gulfstream-to-launch-two-new-business-jets-opportunities-abound/145744.article
