In any case, Ethereum still has a lot of characteristics of a research project. If you follow closely, you start seeing that ideas are explored, some approaches are validated, some are proven impractical, etc. Some delays and hiccups are inevitable. As long as the Ethereum Foundation keeps its transparency and does not overpromise I am fine with it.
