In my opinion they should not rush according to the pressure of the community but focus on the upcoming challenges and to delay it as much as needed.
I'm with you with this. They don't have to rush, it's better to be slowly but surely so that everything will be polished according to what they have promised.
Unlike if they will push it to a quicker implementation with unfinished development. There will be more problems that will be faced in the future if they won't furnished it slowly. We like ETH's problem to be solved and I also think that it's the best way for them to have this development before releasing it.
