There have been parallels appearing now for some time, showing Samsung alongside Nokia's doomed path. Samsung have neglected their software development just as Nokia had (in terms of interface not being iterated and updated). On top of that, hardware has not seen dramatic improvements. The public and loyal journalists have been becoming increasingly disgruntled (since the S4).
If they don't innovate dramatically with the S6 there is trouble on the horizon for this behemoth. Samsung also need to position their experimental products (the new edge and the old round) as their lead products and fully get behind them. I always get the feeling they are hesitant like a person testing the water by dipping their toe in, when they just need to take a dive. The development is done and its in production so why not take a leap. If it fails at least they will be known as a company with innovation at its forefront and they can regress to their current practice.
