It seems unlikely thatanything will be ready. Not one stadium is on schedule, IIRC. None of the airports are progressing as needed. The facilities are poor at best eerywhere. Public transport options are all behind schedule or not started. Facilities for teams, support and visitors are all behind.
I hate to be a pessimist, but this is a disaster in process. We still have debate about whether and how to privatize airports, much less final designs and work started.
It smells like the Pan American games but worse.
