In the auto industry you have PLATFORMS and you have PROGRAMS. Typically an automaker tries to get at least 2 PROGRAMS per PLATFORM. PROGRAMS usually continue for 3 - 4 years until they are refreshed with a new PROGRAM.

Alpha Camaro (not to be confused with Alpha ATS or Alpha CTS) is a PLATFORM. 2016 - 2018 Camaro is a PROGRAM. 2019 - whenever Camaro is a PROGRAM, and will be the 2nd PROGRAM on the Alpha Camaro PLATFORM. Expect it to last at least 3 or 4 years.

During that time, General Motors will make decisions on whether Alpha (including Camaro, ATS and CTS) will undergo change, be replaced by another architecture, continue on as is, or drop. Anyone telling you they know which path GM will take beyond the 3-4 year run of the 2019 refresh of Alpha Camaro is blowing smoke, because none of that will have been decided at this point.

So basically, from the launch of the 2019 refresh, you have 3 - 4 years of Camaro being pretty much what it is, with some model year tweaks.

Hope that helps answer your question.
