Interesting
interview with Martin Prokop. Sorry for google translate, I know it doesn't work very well with Czech.
Apparently the team struggles quite a lot with new car, at least financially.
According to him the new Fiesta is hugely complicated, he had to hire bunch of additional engineers to work on it, and it's much more expensive to maintain and repair than the old car. From his statements it seems like they might not sustain the situation till the end of the season. I seem to remember they planned to have two 2017 Fiestas later this year, which is apparently off the table now.
Doesn't look like the 2017 WRC cars are very privateer friendly.
