Will Embraer C-390 success lead it to larger jets?

Will Embraer C-390 success lead to larger jets?  The company just signed a deal with Sweden for the C390 Millennium military transport, making it the sixth European customer for the aircraft, four of whom are NATO members.  The initial success of the aircraft bodes well for its future, as it appears to be the modern replacement for the venerable but aging C-130 platform.

Several key procurements are coming up that are looking positive for Embraer, including a potential order from India for 80 and Saudi Arabia for 50 aircraft.  Landing those would solidify Embraer

as a key player in this sector, and provide the company both manufacturing and support experience in mainline-sized aircraft rather than simply regional jets, cross-over jets, and business aircraft.

At that point, the natural progression for the company would be to enter into the mainline aircraft market, competing with Airbus and Boeing in the mainline commercial jet market.  Could Embraer become the fourth member of an aviation oligopoly?  We believe they could, as they have virtually all of the technical requirements and a successful reputation in the industry.
